Simplify the given equation.
Ede4ka [16]

Answer:

Part 1) 4-7x=15

The value of x is -\frac{11}{7}

Part 2) x=27

Step-by-step explanation:

Part 1)  Simplify the given equation

we have

6 - (3x + 10)+4(2 - x)=15

In the left side, remove the parenthesis and apply the distributive property

Remember that

(-1)(+1)=-1\\(-1)(-1)=+1

so

6 -3x-10+4(2)-4(x)=15

6 -3x-10+8-4x=15

Combine like terms left side

4-7x=15

Adds 7x both sides

4=15+7x

subtract 15 both sides

-11=7x

Divide by 7 both sides

x=-\frac{11}{7}

Part 2) Solve for x.

5(x + 1) = 4(x + 8)

Apply distributive property both sides

5x+5=4x+32

Group terms that contain the same variable

5x-4x=32-5

Combine like terms

x=27

Label each pair of triangles with the postulate or theorem that proves the triangles are congruent.
Annette [7]

Answer:

<u>Δ MNO ≅ Δ PQR by ASA postulate</u>

Step-by-step explanation:

Δ MNO and Δ PQR are congruents because:

1. Their included sides MN and PR are equal (22 units = 22 units)

2. Their angles ∠M and ∠P are equal  (100° = 100°)

3. Their angles ∠N and ∠Q are equal  (35° = 35°)

<u>Now, we can conclude that Δ MNO ≅ Δ PQR by ASA postulate.</u>

Answer: 0.4 which is choice C

====================================

Work Shown

Focus on the "riverside high school" row only

A = number of twelfth graders = 200

B = number of students = 500

P = probability of picking a twelfth grader

P = A/B

P = 200/500

P = 2/5

P = 0.4
