Steps to solve 7t=x, for t

Answer:

5 books

Step-by-step explanation:

Given that Toni carries upto 18 lbs in her backpack.

The maximum weight Toni can carry is 18 lbs.

Of these 18 lbs, already lunch of 1 lb and gym clothes of 2 lbs are included.

hence available for books is only the remaining 15 lbs.

Total weight in backpack= 18 lbs(Maximum)

Weight of lunch = 1 lb

Weight of her gym clothes = 2 lb

Hence maximum weight available for books = 18-(1+2) = 15 lbs

Weight of one book = 3 lbs.

No of books she can carry = 15/3 = 5 books

Answer:

[tex]4.5a^6d^2[/tex]

Step-by-step explanation:

Use:

[tex](ab)^n=a^nb^n\\\\(a^n)^m=a^{nm}\\\\a^n\cdot a^m=a^{n+m}\\\\\dfrac{a^n}{a^m}=a^{n-m}\\\\a^0=1\ for\ a\neq0[/tex]

----------------------------------------------------------------------------------

[tex]\dfrac{(3a^3b^{-2}c^0d)^3}{6a^3b^{-8}c\cdot b^2d}=\dfrac{3^3(a^3)^3(b^{-2})^3(1^3)d^3}{6a^3b^{-8+2}d}=\dfrac{27a^9b^{-6}d^3}{6a^3b^{-6}d}\\\\=\dfrac{27}{6}a^{9-3}b^{-6-(-6)}d^{3-1}=4.5a^6b^0d^2=4.5a^6d^2[/tex]

So, this is a rate per person * number of people.

So,

$916 per person * 72 people = 65,952

The city pays $916 per year for health insurance for;

each of 72 municipal employees

So;

1 municipal employee gets ⇒ $916

72 employees get ⇒ How much?

Cross multiplying gives:

72/1 × $916 = $65,952

The total cost the city pays per year is $65,952.

The answer us A.

Line AC needs to be congruent to DF because for SAS (side angle side) we have a side (BA and DE) and an angle (A and D) so we need another side.

Answer:

A. [tex]\overline{AC}\cong \overline{DF}[/tex].

Step-by-step explanation:

We have been given image of two triangles ABC and DEF. We are asked to find the information that will show that both triangles are congruent by SAS.

We know that two triangles are congruent by Side-Angle-Side congruence, if two sides and included angle of a triangle is equal to two sides and included angle of the other triangle.

We can see that angle A is included angle of side AB and AC, while angle D is included angle of side DE and DF.

We have been given that angle A is congruent to angle D and side AB is congruent to side DE.

To be both triangles congruent by SAS congruence, side AC must be congruent to side DF, therefore, option A is the correct choice.

Answer:

The correct option is:  A

Step-by-step explanation:

The given equation is:  [tex]y= 2x-3[/tex]

If [tex]x=0[/tex], then [tex]y=2(0)-3 = 0-3=-3[/tex]

If [tex]x=1[/tex], then [tex]y=2(1)-3 = 2-3=-1[/tex]

If [tex]x=2[/tex], then [tex]y=2(2)-3 = 4-3=1[/tex]

So, the points on the graph of the given equation are:  (0, -3), (1, -1) and (2, 1)

According to the below graph, those points are on a straight line.

Thus, the correct option will be:  A. It is a linear function because the graph contains the points (0, −3), (1, −1), (2, 1), which are on a straight line.

Answer:

A. It is a linear function because the graph contains the points (0, −3), (1, −1), (2, 1), which are on a straight line.

Answer:

B) angle 3

Step-by-step explanation:

Corresponding angles are angles that are in the same relative position to the parallel lines and in the same relative position to the transversal.

∠7 is below the parallel line it is beside, and is on the left hand side of the transversal.  The matching, or corresponding, angle will be below the other parallel line and also on the left hand side of the transversal.  This is ∠3.

The ∠3 is corresponds to angle 7.

It is required to find the angle corresponds to angle 7.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle and corner whether constituting a projecting part or a partially enclosed space.

Given:

Corresponding angles are the pairs of angles that are found in the same relative position on different intersections. It is formed when a transversal passes through two lines.

∠7 is below the parallel line it is beside, and is on the left hand side of the transversal.  The matching, or corresponding, angle will be below the other parallel line and also on the left hand side of the transversal.  This is ∠3.

i.e ∠3=∠7

Therefore, the ∠3 is corresponds to angle 7.

Ah, this is an example of the distribution property, as you would need to distribute the 5 to the 8 and 3. Here's the step-by-step process:

[tex]5(8+3)[/tex]

Let's first multiply the 5 and 8

[tex]5(8)=40[/tex]

Now, the 5 and 3

[tex]5(3)=15[/tex]

We now have two whole numbers, and therefore our answer:

An inverse variation can be represented by the equation

[tex]xy=k\to y=\dfrac{k}{x}[/tex]

We have

[tex]\dfrac{y}{6}=x\qquad|\cdot6\\\\y=6x[/tex]

Answer: The relationship does not show an inverse variation.

Answer: Each multiple choice question is worth 5 points.

Step-by-step explanation: You can find this answer by using the equation "14m + 24 = 16m + 14" and then solving for "m". To find what "m" is, you must first subtract 14m from both sides, leaving "24 = 2m + 14". Next, you subtract 14 from both sides, leaving "10 = 2m". Finally, you divide both sides by 2, which will give you "m = 5". Thus meaning each multiple choice question is worth 5 points.

To check this, simply fill in for "m" and solve each side. 14 * 5 + 24 = 94 and 16 * 5 + 14 = 94. 94 = 94, so "m = 5" is correct.

I hope this helps!

Some number y has 7 subtracted off to get 15. We have y-7 = 15. To isolate y, we have to undo the "subtract 7" operation that happens to y. We have to add 7 to both sides.

y-7 = 15

y-7+7 = 15+7

y = 22 is the answer

Hello!

Raising 2 to the 7th power gives 128, and the sum of this result with a variable r is expressed as 128 + r.

To raise 2 to the 7th power, you multiply 2 by itself 7 times—2 x 2 x 2 x 2 x 2 x 2 x 2. The result of this calculation is 128. Now to find the sum of this result and r, you simply add r to 128, which can be represented as 128 + r. This expression signifies the sum of 2 raised to the 7th power and a variable r.

2x+16=3x-12

16+12=3x-2x

28=x

now,since this is a fig of 2 parallel line with a bisector then line EF =180 degrees.

therefore,3x+12+y=180

3(28)+12+y=180   [we already found the value of x]

96+y=180

y=180-96

y=84.

Hello!

[tex]\frac{-4s}{-4}=\frac{9}{-4}[/tex]

[tex]s=-\frac{9}{4}[/tex]

Explanation: This question is super easy for me. First you had to do add 1 from both sides. It gave us -1-4s+1=8+1, then simplify, and it gave us -4s=9. You can also divide by -4 from both sides. It gave us -4s/-4=9/-4, and simplify. And the answer it gave us is s=-9/4 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly.

I believe that “b” would equal 6

First you use the formula (-b/2a) to find the axis of symmetry(or the x value) and then you plug that into the equation to find the y value.

a = 2

b= -16

16/2(2)=16/4=4

(4, x )  so we have the x-value and now we plug 4 into the original equation

y=2(4)^2-16(4)+8

y=2(16)-64+8

y=32-64+8

y=-24

So the vertex is at (4,-24)

Answer:

It is -11

if that sign (parenthesis) is there it means that the 6 is turned into a positive number. but the -5 is still negative so you just add 5+6=11 and you jhave to add the negative

PLZZ MARK BRAINIEST BECUZ I EXPLAINED AND PLZ THANK ME!!!

2=320

320/2=  160

Key:

*1=160

3*160=480

4*160=640

12*160= 1920

Working together for the same time, 3 combine harvesters can harvest 480 acres, 4 combine harvesters can harvest 640 acres, and 12 combine harvesters can harvest 1920 acres.

If two combine harvesters can harvest 320 acres in a certain amount of time, we need to find out how many acres can be harvested by 3, 4, and 12 combine harvesters working together for the same amount of time.

1. **Three combine harvesters**:

  Since 2 combine harvesters can harvest 320 acres, the harvesting capacity per harvester is:

  - 320 acres / 2 harvesters = 160 acres per harvester in the given time.

  Therefore, 3 combine harvesters can harvest:

  - 3 harvesters * 160 acres per harvester = 480 acres.

2. **Four combine harvesters**:

  Similarly, 4 combine harvesters can harvest:

  - 4 harvesters * 160 acres per harvester = 640 acres.

3. **Twelve combine harvesters**:

  Similarly, 12 combine harvesters can harvest:

  - 12 harvesters * 160 acres per harvester = 1920 acres.

In summary, working together for the same time, 3 combine harvesters can harvest 480 acres, 4 combine harvesters can harvest 640 acres, and 12 combine harvesters can harvest 1920 acres.

To simplify the given expression, distribute the fractions and combine like terms. The final simplified expression is 1/x + 24.

To simplify the given expression 1/2 (3/5x - 8) + 7/4 (2/5x + 4), we need to distribute the fractions across the terms. First, distribute 1/2 across 3/5x and -8, then distribute 7/4 across 2/5x and 4. This results in (3/10x - 4) + (14/20x + 28). Now, combine like terms by adding the coefficients of x. Thus, the simplified expression is (3/10x + 14/20x) + (-4 + 28).

To add the fractions (3/10x + 14/20x), we need to find a common denominator. The least common multiple of 10 and 20 is 20. Multiply the numerator and denominator of the first fraction by 2 and the numerator and denominator of the second fraction by 1 to obtain (6/20x + 14/20x). Now, add the fractions together to get (20/20x), which simplifies to 1/x.

Combine the constants (-4 + 28) to get 24. Therefore, the simplified expression is 1/x + 24.
