26/40 = 13/x
26x = 520
x = 520/26
x = 20 <== ur answer
Number Two:
The formula to find the volume of a triangular prism is the area of the triangle/base multiplied by the height.
Finding the area of the base:
10×15=150×0.5=75
Now multiply it by its height.
75×25
1,875 m³
Number Four:
You need to multiply the width times the height times the length, or in any arrangements. Everything needs to get mutiplied together.
1×2.5
2.5×9
22.5 cm³
No, because (2,0) is a coordinate. x=2 and y=0. So just plug in the numbers where there's x or y with the appropriate number, (2 or 0). So in the first equation, x-2y=0, when you pug in the numbers, 2-2(0)=0, you know it's wrong because 2-0=0 isn't correct. So no. the point (2,0) is not a solution to the first equation. Now plug in the numbers for the second coordinate. You get 2(2)-3(0)=1. So 4-0=1. This is once again false no no. (2,0) satisfies neither equations.
Answer:
The answer is D
Step-by-step explanation:
The solution of two equations is the point where their lines intersect.
