Answer:
[A] 18
Explanation:
[I'm assuming you want us to find the measure of ∠ABC]
∠ABC is a right angle, meaning ∠ABD and ∠DBC added together must equal 90°
2x° + 3x° = 90
2x + 3x = 5x
5x = 90
5x / 5 = 90 / 5
x = 18
The second one. Do the math. .35 x 63 = 22.05
Answer:
The number is 10
Step-by-step explanation:
Let x be the number
product is multiply
12 + (2x) = 4x -8
Subtract 2x from each side
12+2x-2x = 4x-2x-8
12 = 2x-8
Add 8 to each side
12+8 = 2x-8+8
20 = 2x
Divide by 2
20/2 = 2x/2
10 =x
Answer:So that's the change in Y. Now notice that X is increasing. By one unit each time. So we can calculate the slope. The slope is the change in Y divided by the change in X
