Solve for x. 3x-(5-2x)=x-21

Answer:

B = 68°  and  C = 22°

Step-by-step explanation:

Let angle B's measure be B and angle C's measure be C.

Also note that complementary means that they sum to 90.

Now:

The m∠B is two more than three times the measure of ∠C:

we can write:

B = 3C + 2

If ∠B and ∠C are complementary angles:

B + C = 90

Putting 1st equation in 2nd, we get:

B + C = 90

3C + 2 + C = 90

4C = 90 - 2

4C = 88

C = 88/4 = 22

Now B = 3C + 2, so

B = 3(22) + 2 = 68

Hence, B = 68 degrees and C = 22 degrees

The letter J is formed by the opposition movement of the thumb toward the fingers of the same hand.

Explanation:

The subject of this question is Biology, specifically the anatomy of the hand and the movement of the thumb.

The letter J is formed by sticking up the smallest finger and folding all the other fingers into the palm of your hand with the thumb folded over them. This hand movement is an example of the opposition movement of the thumb toward the fingers of the same hand, which allows us to grasp and hold objects.

The thumb joint, which can move back and forth and up and down, but more freely than the wrist or fingers, plays a key role in the formation of the letter J.

Answer:

The measure of angle L is 40°

Step-by-step explanation:

we know that

In a parallelogram the opposite angles are congruent and the opposite sides are congruent and parallel

see the attached figure to better understand the problem

so

In this problem

∠L≅∠N

∠M≅∠O

we have

∠L=(3x-20)°

∠N=(2x)°

so

equate the angles and solve for x

[tex]3x-2x=20[/tex]

[tex]x=20[/tex]

Find the measure of angle L

Answer: what the other guy said

Step-by-step explanation: yea

Answer:

Step-by-step explanation:

speed = distance/time

so renaldo speed = 3.2/0.5 = 6.4miles/hr (since time taken is 1/2 hr)

now after 1 hr of his appoinment i.e at 5:30pm he took bus whose speed is same as before i.e 6.4 miles/hr

now time taken to cover this 4.8 miles = 4.8/6.4 = 3/4 hr (since time = distance /speed )

3/4 hr = 3/4 * 60 = 45 minutes

so he reached at 6:15pm . so he will be on time.

Answer:

for tomas 19.100-6.15=$13.85dollars

so tomas's shirt cost $13.85

for kyle 9.100-1.06=$8.94

13.85-8.94=4.91

so tomas's shirt $4.91more than Kyle's shirt

Answer:

Tomas's shirt costs $4.91 more than Kyle's shirt.

Step-by-step explanation:

It is given that Tomas gave the cashier a $20 bill and received $6.15 in change. So, the cost of Tomas's shirt is the difference between the amount he gave and he received in change.

Cost of Tomas's shirt = $20 - $6.15 = $13.85

Kyle gave the cashier a $10 bill and received $1.06 in change. So,

Cost of Kyle's shirt = $10 - $1.06 = $8.94

The cost of Tomas's shirt is $13.85 and the cost of Kyle's shirt is $8.94.

Cost of Tomas's shirt is more that the cost of Kyle's shirt.

$13.85- $8.94=$4.91

Therefore, Tomas's shirt costs $4.91 more than Kyle's shirt.

Final answer:

The expression 80 + (-22 4/15) is solved by converting the mixed number to an improper fraction, aligning the fractions by the same denominator, and then adding them to get 58 4/15 as the result.

Explanation:

To solve the expression 80 + (-22 4/15), follow these steps:

First, convert the mixed number -22 4/15 into an improper fraction. To do this, multiply the whole number by the denominator and add the numerator: (-22 × 15) + 4 = -330 + 4 = -326, so the mixed number becomes -326/15.

Next, since 80 is a whole number, we can convert it into a fraction with the same denominator of 15 to make it easier to add to -326/15. To do that, multiply 80 by 15/15, which is the equivalent of 1, to get the fraction 1200/15.

Now, add the two fractions: 1200/15 + (-326/15) = (1200 - 326)/15 = 874/15.

This fraction can be simplified back into a mixed number by dividing the numerator by the denominator: 874 ÷ 15 = 58 with a remainder of 4, so the mixed number is 58 4/15.

Therefore, the solution to the expression 80 + (-22 4/15) is 58 4/15.

a.  [tex]\frac{1}{20}[/tex] liters per glass

b. 50 milliliters

To find the amount of water in each glass, divide the total amount of water by the number of glasses, resulting in [tex]\frac{1}{20}[/tex] liters per glass. To express this in milliliters, multiply by 1000 to get 50 milliliters per glass.

a. To find the amount of water in each glass, divide the total amount of water ([tex]\frac{1}{4}[/tex] liters) by the number of glasses (5): [tex]\frac{1}{4}[/tex] ÷ 5 = [tex]\frac{1}{20}[/tex] liters per glass. Drawing a visual representation can help understand this partitioning.

b. To express the amount in milliliters, we know that 1 liter is equal to 1000 milliliters. So, [tex]\frac{1}{20}[/tex] liters per glass = ([tex]\frac{1}{20}[/tex]) * 1000 milliliters = 50 milliliters per glass.

To distribute the 250 milliliters equally into 5 glasses, we divide 250 milliliters by 5. This calculation results in:

250 milliliters ÷ 5 = 50 milliliters per glass.

To convert the amount in milliliters back to liters for each glass, recall that 1,000 milliliters is equivalent to 1 liter. Therefore, 50 milliliters is the same as 0.05 liters (since 50 divided by 1,000 equals 0.05).

The question is:

A pitcher of water contains [tex]\frac{1}{4}[/tex] liters of water. The water is poured equally into 5 glasses.

Answer:

Step-by-step explanation:

2(3x + 6) = 42

(3x + 6) = 42/2

(3x + 6) = 21

3x + 6  = 21

3x  =  21 - 6

3x  =  15

x = 1/3

x = 5

Answer:

The answer would be x=5

Step-by-step explanation:

2(3x+6)=42

so what you're gonna do is use the distributive property, so you would multiply 2 and 3x, and 2 and 6. so then you would have:

6x+12=42

Now you want to get rid of the twelve so you can solve for x. So you are going to subtract 12 from 12 and 42. So now you have:

6x=30

Next you're going to divide 6x and 30 by 6. So you would have x=5

Answer:

The correct option is the last one (0,84 grams, because (5.04 × 1.67) × (10^23 x 10^-24) = 8.4168 x 10^-1))

Step-by-step explanation:

The first step is to think that you have to multiply the number of atoms for the weight of each atom.

When you work with scientific notation, you should solve the operation for numbers and for the ten base. In this case you solve 5.04 x 1.67 and then the product of the ten bases. For this product you have to sum the exponents of the ten base 23 + (-24) = -1.

Summarizing.... 5.04 x 10^23 x 1.67 x 10^-24 = (5.04 x 1.67) x (10^23x10^-24)  ⇒ 5.04 x 10^23 x 1.67 x 10^-24 = 8.4168 x 10^-1

⇒ 5.04 x 10^23 x 1.67 x 10^-24 = 0,84168.
