If you would like to know which of the following steps should be performed to eliminate variable d first, you can find this using the following steps:
equation a: 2c = d - 8 /*(-3)
equation b: c = 3d + 8
__________________
-6c = -3d + 24
c = 3d + 8
__________________
-6c + c = -3d + 24 + 3d + 8
-5c = 32
5c = -32
c = -32/5
<span>The correct result would </span>be: <span>multiply equation a by −3.</span>
Answer: BE = 48 cm
Step-by-step explanation:
BE is twice as long as AB so to find BE just multiply 2 by 24.
2 × 24 = 48
Because each of these angles are 90 degrees, we know they're each equal to each other.
Let's find the value of the variable y first.
We can use 5y - 17 = 2y + 50 to find the value of y.
5y - 17 = 2y + 50
-2y from both sides
3y - 17 = 50
+17 to both sides
3y = 67
Divide both sides by 3
y = 22.33
Now we need to find the value of x.
x + 44 = 7x - 248
-x from both sides
44 = 6x - 248
+248 to both sides
292 = 6x
Divide both sides by 6
x = 48.67
And there's your variables.
y = 22.33
x = 48.67
I’m not sure this is right, but at least I tried?
