<span> 4x+7=5
subtract 7 on both sides
4x = -2
divide both sides by 4
x = -2/4
simplify
x = -1/2</span>
Equation: ___is__. _%__ of. 100 = 100. % _______. _____ 80. 100 Cross multiply the 100s = 1000 and divide by 80. 1000÷80 = 80. Answer = 80%
step 1
Subtract 14 from 50
50-14=36
so
If you solve for p
the answer is the second option
Since you know Z = 2, you can plug it into:
Y = 5 · Z²
Y = 5 · (2)²
Y = 5 · 4
Y = 20
Now that you know Y = 20, you can plug it into:
X = 2 + 5Y
X = 2 + 5(20)
X = 2 + 100
X = 102
Now that you have X, plug it into "2+2X=?"
2 + 2x = ?
2 + 2(102) = ?
2 + 204 = ?
206 = ?
Y= mx+ b, the y- intercept is b. It equals whatever point is on the y-axis
