X+3 = 7.5
x =7.5-3
x= 4.5
x^2 +3x-7
= (4.5)^2 +3(4.5) -7
= 20.25 +13.5 -7
=26.75
Answer:
Step-by-step explanation:
Remark
Let the shorter base = x
Let the longer base = 3x
h = 5
Area = 60
Formula
Area = (b1 + b2)*h /2
Solution
60 = (x + 3x)*5 / 2 Multiply both sides by 2
2*60 = (x + 3x)*5 Combine like terms
120 = 4x *5
120 = 20x Divide by 20
120/20 = x
x = 6
Therefore the two bases are
x = 6
3x = 18
Answer:
C.
3 units to the right would mean you are adding the positive value of 3 to the number 5
Answer:
x = 12.85
Step-by-step explanation:
<u>Step 1: Solve for x by adding 7.57 to both sides</u>
x - 7.57 + 7.57 = 5.28 + 7.57
x = 12.85
Answer: x = 12.85
If $36 is spent buying 9 movie tickets we can do 36/9 to get $4/ticket. That means if we're talking about two tickets, it's $8/2 tickets.
Hopefully this helped!
