Answer:
2y = 3x + 21
y = 1.5x + 10.5
plug in, in the second equation
- 4x + (1.5x + 10.5) = 23
-4x + 1.5x + 10.5 = 23
-2.5x + 10.5 = 23
-2.5x = 12.5
x = 12.5/-2.5 = -5
y = 1.5 (-5) + 10.5 = 3
x = -5
y = 3
The correct answer would be $66
Answer:
8.75$
Step-by-step explanation:
if 12 cans cost $21
1 can cost $21÷12=1.75$
5 cans = 1.75$ ×5
Seems like your question is quite incomplete, I bet here is the missing part *<span><or = 22.12 for the width w in inches of a desk drawer.
According to the fact that </span><span>abs(w-22) should be less than equal to 12, the answer should have a look like this : </span><span> Iw - 22I < or = 0.12. I am pretty sure it will help you.
Next time check it carefully. Regards!</span>
Answer:
by using Pythagoras law
height =√{10²-(26-14)²}=±2√11=+2√11
the area of the trapezoid=1/2 height (side1+side2]
=1/2 ×2√11 (14+26)=132.66unit²
Step-by-step explanation:
greater than 132.66unit² is 160 unit² so answer is 160unit²
