Write And Solve An Equation That Can Be Used To Find X, In The Figure Below:

Answers

Answer 1

Answer: x=40

Step-by-step explanation:

so you would add the two angles you already know.

30+63=93

The sum of the angles of a triangle is always 180°. Knowing this, you can do

180-93=87

so you know the third angle is 87°

plug this into the equation: 2x+7

2x+7=87

subtract both sides by 7

2x=80

divide by two

x=40

Answer 2
The correct answer is X=40 because

1. Add the 2 angles you already know.

30 + 63 = 93

2. The sum of all angles in a triangle is always 180°

180 - 93 = 87

3. third angle is 87°

2x + 7 = 87

4. Subtract BOTH sides by 7

2x = 80

5. Divide by 2

X = 40

Jake and Finn both worked hard over the summer. Together they earned a total of $400. Finn earned $25 more than Jake.
(a) Graph the equations in the system.
(b) Use your graph to estimate how much each person earned. How much did each person earn?

Answers

Answer:

F = 212.5  

J = 187.5

My way is weird but i divided each side by 2 and subtracted 25 from jake and added 25 to finn. Then distributed 25 for each.

ex: 175 + 12.5 = 187.5.

225 - 12.5 = 212.5.

Add them both and you get 400.

Which of the following expressions represent 15% tip on a $20 meal? Which represents the total bill? **Select all that apply**. Explain your reasoning for the choices you select.

A.) 1520
B.) 20+0.1520
C.) 1.1520
D.) 1510020

Answers

Answer:

15/100 * 20, because the meal is 20 dollars and to find the percent of something you divide it with 100 so you will divide 15 with 100 and you’ll get 0.15. Then you will times it with the amount the meal cost because thats the charge. So 0.15•20 and you’ll get $3. A 15% tip for a $20 meal is $3.

1. find the value of the square root of 16/4
2. find the value of the square root of 16 over the square root of 4.
3. Is the value of the square root of 16 over the square root of 4, the same as the value of the square root of 16/4?
