Answer:
y = -6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
0.75y−1.5y+0.5=5
0.75y+−1.5y+0.5=5
(0.75y+−1.5y)+(0.5)=5(Combine Like Terms)
−0.75y+0.5=5
−0.75y+0.5=5
Step 2: Subtract 0.5 from both sides.
−0.75y+0.5−0.5=5−0.5
−0.75y=4.5
Step 3: Divide both sides by -0.75.
Hope this helps!

You’re answer should be 60
Answer:
SA = 1,176 ft².
Step-by-step explanation:
To find the surface area of the triangular prism, we can solve for the rectangular base, both triangular faces, and lateral sides separately.
For the rectangular base: (Use formula l×w)
20 × 18 = 360 ft²
For the triangular faces: (Use formula 1/2(b·h)
1/2(18 × 12) = 108 ft²
Since there are two faces, we need to double the amount.
108 × 2 = 216 ft².
Finally, solve for the lateral sides:
20 × 15 = 300 ft².
There are two sides, so:
300 × 2 = 600 ft².
Add up all of these areas:
600 + 216 + 360 = 1,176 ft²
You use PEMDAS. Start by distributing the terms in the parentheses. The isolate the variables. To do that you subtract x from one side of the equation to the other side. You always do the other operation. If it is adding you subtract, if your multiplying your dividing and the other way around. Then you subtract 10 from each side. This equation has many solution because all the terms cancel out.
