Answer:
t = -7
Step-by-step explanation:
You have to get t by itself. Just take the 12 and subtract it from both sides. 5-12 on the left and 12-12 on the right. You then end up with -7 = t or t = -7.

What is the equation of the line —3x – 2y = 30 in slope-intercept form?
Answer:
2nd option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
- 3x - 2y = 30 ( add 3x to both sides )
- 2y = 3x + 30 ( divide terms by - 2 )
y = - [tex]\frac{3}{2}[/tex] x - 15 ← in slope- intercept form

I really need help finding the solution!!
Answer:
-0.5 is not a solution
2 is a solution
Step-by-step explanation:
To check if something is a solution of the equation, you need to substitute the value in place of the variable
15 + 2y = -12 - 4y
15 + 2(-0.5) = -12 - 4(-0.5)
15 - 1 = -12 + 2
14 ≠ -10 ∴ -0.5 is not a solution
5 - 2(3x + 5) = 3 - 10x
5 - 2[3(2) + 5] = 3 - 10(2)
5 - 2(6 + 5) = 3 - 10(2)
5 - 12 - 10 = 3 - 120
-17 = -17 ∴ 2 is a solution

0.35x = 21
x = 60
Answer:
Step-by-step explanation:
a, 85% of 80
85% of 80
= 85/100*80
=85/100*80
=0.85*80
=68.
b, 21 is 35%
21 is 35%
=21*35/100
=21*0.35
=7.35.
