Twice a number decreased by 8 is 2 less than half the number. What is the number?

Multiply both sides by 7

1/7 r ×7 = 10 ×7

7r/7 = 70

r = 70

Multiply both sides by 7  

1/7 r ×7 = 10 ×7

1r  = 70

Divide by 1 on both sides (Side by Side need to divide)

r = 70

There aren't any lines of symmetry because it is a scalene right triangle. (:

Answer:

The scalene triangle has no lines of symmetry.

Step-by-step explanation:

We can see that the given figure is a scalene right triangle.

A line of symmetry is a line that divides a figure into two mirror image halves. The line around which a figure is reflected over is called a line of symmetry.

The scalene triangle has no lines of symmetry. A scalene triangle is one which has no sides equal and no angles equal.

X/-3 -41 = -11

X/-3 = -11 +41

X/-3 = 30

X = 30×-3 = -90

To check

Put X = -90 in LHS

-90/-3 - 41

30 - 41

-11 = RHS

Final answer:

To find Mikhail's age, set up the equations based on the given information; Gabrielle's age is twice Mikhail's and their combined age is 66. Solving the equations shows that Mikhail is 22 years old.

Explanation:

The given problem is about determining Mikhail's age when Gabrielle's age is two times Mikhail's age and together their ages sum up to 66. We can set up equations to solve this problem. Let's denote Gabrielle's age as G and Mikhail's age as M.

From the problem we have two equations:

G = 2M (Gabrielle is twice as old as Mikhail)

G + M = 66 (Sum of their ages)

We can substitute the first equation into the second:

2M + M = 66

3M = 66

M = 66/3

M = 22

Therefore, Mikhail's age is 22 years old.

we know 140 is 5% of some number x. to find x, we use this formula: 140/x = 5/100

Answer:

Option. B is not describing the a rigid transformation.

Step-by-step explanation:

Rigid transformation means an object when moved from one point to another, its position may change but size and shape of the object remains unchanged.

By this definition,

Option A. translating a figure 4 units up

In this statement only place is moving not the size, so it's Correct (describing rigid transformation)

Option B. Enlarging a figure by a scale factor of 2.

In this option size of the object is enlarged by a scale scale factor of 2, so this option is Not correct (not describing rigid transformation)

Option C. Rotating a figure by 180°

Again place is changing so its describing the rigid transformation. Correct (describing rigid transformation).

Option D. Reflecting a figure across the y axis.

Reflection means change in place. So the option is Correct (describing rigid transformation).

Missy should receive $0.00 in change.

To determine the change Missy should receive, we need to subtract the total amount she plans to pay from the cost of her food and the tip. If Missy's french toast costs $13.00 and she plans to leave a $7.00 tip, the total amount she plans to pay is $13.00 + $7.00 = $20.00. Since she pays with a $20.00 bill, the change she should receive is $20.00 - $20.00 = $0.00.

Answer:

[tex]\displaystyle Yes[/tex]

Step-by-step explanation:

According to the Divisibility Rules, any number quantity ending in 8, 4, 6, 4, 2, or 0, is divisible by 2.

I am joyous to assist you anytime.

If the expression represents the distance between -14.6 and -5.2 on the number line. The expression that represents the distance between -14.6 and -5.2 on the number line is 9.4.

What is distance?

Distance between these two points:

Distance = Larger value - Smaller value

Where:

Larger value = -5.2

Smaller value=  -14.6

So,

Distance = -5.2 - (-14.6)

Distance = -5.2 + 14.6

Distance = 9.4

Therefore the expression that represents the distance between -14.6 and -5.2 on the number line is 9.4.

First you had to subtract by seventeen from both sides of equation form.

[tex]17+p-17=7p-13-17[/tex]

Then simplify.

[tex]p=7p-30[/tex]

Next, subtract by seven-p from both sides of equation form.

[tex]p-7p=7p-30-7p[/tex]

Simplify.

[tex]-6p=-30[/tex]

Then you divide by negative six from both sides of equation form.

[tex]\frac{-6p}{-6}= \frac{-30}{-6}[/tex]

And finally, simplify by equation.

[tex]-30/-6=5[/tex]

Final answer: [tex]\boxed{p=5}[/tex]

Remark

The difference is between any two terms. You should pick t3 and t4 which are both positive. That's easier to handle than a couple of minus signs.

d

t4 - t3 = d

13 - 5 = d

8 = d

a

the first term is - 11

Formula

t_n = a + (n-1)*d

t_n = -11 + (n-1)*8

Check

t_n = - 11 + (3-1)*8

t_3 = - 11 + 16

t_3 =  5 which it does.

Try t_5. It should be 21

t_5 = - 11 + (5 - 1)*8

t_5 = - 11 + 4 * 8

t_5 = -11 + 32

t_5 = 21

Answer

t_n = -11 + (n - 1)*8

Slope = 0.2 and  y-intercept = 0.3

The slope intercept form of line is

y=mx + b where m is the slope and b is the y intercept

So equation becomes  y = 0.2 x + 0.3

To find coordinates of 4 points , we plug in some number for x  and find out y

x              y = 0.2 x + 0.3

0              y = 0.2 (0) + 0.3= 0.3

1               y = 0.2 (1) + 0.3= 0.5

2               y = 0.2 (2) + 0.3= 0.7

3               y = 0.2 (3) + 0.3= 0.9

Four coordinates are (0,0.3) (1,0.5) (2,0.7) (3,0.9)

I had a different  A pex  question but it was still relatively the same answer but i don't want anyone getting the answer wrong due to confusion so my answer was

Answer: T(c)=c+160/4

The function T(c), which is the inverse of C(t), is T(c) = (c + 180) / 6.

To find the inverse function T(c), we first have to rewrite the original function C(t) in terms of c. So, if C(t) = 6t - 180, we write it as c = 6t - 180.

Next, we swap the roles of c and t, so now t becomes the function of c i.e., we get t = 6c - 180.

Finally, we solve this equation for c to get the inverse function. Doing so will give us c = (t + 180) / 6. Hence the inverse function is T(c) = (c + 180) / 6.
