Answer:
Step-by-step explanation:
24)
200= 3(21) + 4x
200= 63 +4x
-63 -63
137= 4x
divide each side by 4
34 = x

25)
.5(pi)= about 1.6
1.6(2.5)= 4

44)
equation- T= 12.17+0.75v
105.75= 12.17 + .75v
-12.17 -12.17
93.58= .75v
divide each side by .75
answer 125
Answer:
4) slope= 0
5) 
Step-by-step explanation:

4) Slope


= 0
The slope is zero as the line is a horizontal line (since both points have the same y-coordinate of 10).
5) Slope



Since you have taken (x₁, y₁) to be (9, 4), the value of x₁ should be 9 instead of 2.
Answer:
X= 15
Step-by-step explanation:
multiply 5 on x/5 and 9
divide 3 and 45
x=15
Answer:
90 cents
Step-by-step explanation:
Find how much money you have by plugging in 18 as n into the expression:
5n
5(18)
Multiply:
= 90
So, when you have 18 nickels, you have 90 cents
Answer:
D) x=6√3, y=3√3
Step-by-step explanation:
Given both triangles are 30-60-90 triangles, this means that the length of y will be 9/√3=√81/√3=√(81/3)=√27=3√3
This also means that x will be twice the length of y which means x=2y=2(3√3)=6√3
This means that the correct answer is D) x=6√3, y=3√3
Refer to the diagram below to understand where I got these lengths.
