Answer:

<u>X=15</u>

Explanation: You have no like terms to combine and are at the last step of the algebraic equation. So, you would divide 7 on both sides. 7 by 7 cancels it out and 105 divided by 7 equals 15. Hope this helps ^-^.

Pls help, and hurry. i will give anyone brainliest if you give the correct answer.
Anna11 [10]

Answer:

Two answers:

22 ≥ v

OR

v ≤ 22

Step-by-step explanation:

It's the same as solving for a variable in an equality. Imagine it as 17 = v - 5 for a moment. Simplify by subtracting 5 from both sides and re-add the inequality sign. This can be easily done since we are not multiplying or dividing, just adding and subtracting.

The triangle and the trapezoid have the same area. Base b2 is twice the length of base b1. What are the lengths of the bases of
Xelga [282]

Answer:

b_1 \approx 7.2

b_2 \approx 14.4

Step-by-step explanation:

Given

Area = 65cm^2 --- Area of the triangle

b_2 = 2b_1 --- the bases of the trapezoid

The missing parameters is:

h=6 cm --- Trapezoid height

Required

Determine b1 and b2

Since the areas of the trapezoid and the triangle are the same, then:

Area = \frac{1}{2}(b_1 + b_2) *h

So, we have:

65 = \frac{1}{2}(b_1 +b_2) * 6

Substituteb_2 = 2b_1

65 = \frac{1}{2}(b_1 +2b_1) * 6

65 = \frac{1}{2}(3b_1) * 6

65 = 3b_1 * 3

65 = 9b_1

Solve for b_1

b_1 = \frac{65}{9}

b_1 \approx 7.2

Substitute b_1 \approx 7.2 in b_2 = 2b_1

b_2 \approx 2 * 7.2

b_2 \approx 14.4
