Answer:
x= 3, y= -2
Step-by-step explanation:
5x+3y= 9
x= 25÷7 + 2÷7 y
5(25÷7 +2÷7 y)
5( 25÷7 +2÷7 y ) + 3y= 9
y= -2
x= 25÷7 + 2÷7 x (-2)
x= 3
Answer: Dimensions are given as below:
Length = 236 yards
width = 144 yards
Step-by-step explanation:
Let the width be x
then length = 92 more than x = 92+x
formula for perimeter of rectangle = 2 [ length + width]
therefore
760 = 2 [ 92+x + x ]
760 = 2 ( 92+2x )
760 = 184 + 4x
4x = 760 - 184
4x = 576
x= =
x = 144
So width = 144 yards
Length = 144+92 = 236 yards
Answer:
(-7, 3) i think, not 100% sure
Step-by-step explanation:
I got B but I'll show you how I got that answer.
Let's look at AB and BC. AB = 3 and BC = 4.
3/4 = 0.75
On the triangle, AB = 90. And BC = 10x - 20. We need to solve for x and prove that AB/BC = 0.75.
Let's start with Choice A.
10(11) - 20 = 90.
AB = 90
BC = 90.
90/90 = 1. It doesn't equal 0.75. Meaning this answer is wrong.
Now let's look at Choice B.
10(14) - 20 = 120.
AB = 90
BC = 120
90/120 = 0.75
So, 3:4 = 90:120 making Choice B the correct Answer. Let me know if this is correct
