Step-by-step explanation:
is there any drawing beside it ? pls ..the first X is equal to the second x ?
Answer:
I think x=8
Step-by-step explanation:
5(x+7)+15=90
90 because it's a 90 degree angle
5x+35+15=90
5x+50=90
5x=40
x=8
To solve this, you will have to set up your equation as fractions:
X is to 4 as 4 is to 4+3, or 7
X/4 = 4/7
You will then cross multiply
7x = 4•4
7x = 16
Divide.
X = 2.285714...
Round to the nearest hundredth.
2.29
Answer:
<h3>(5y-3)/2</h3>
Step-by-step explanation:
Given the equation 2x+ 3 / 5= y
Cross multiply
2x+3 = 5 * y
2x+3 = 5y
Subtract 3 from both sides
2x+3-3 = 5y - 3
2x = 5y-3
Divide both sides by 2
2x/2 = (5y-3)/2
x = (5y-3)/2
Hence the value of x is (5y-3)/2
I feel like I just solved this one. its -1 isn't it?
