-55 is the value of the expression 5m+10(m-1) when the value of m is -3.
The given expression is 5m+10(m−1).
We need to find the value of expression when m is -3.
Let's substitute the value of m=−3 into the expression 5m+10(m−1):
5m+10(m−1)
=5(−3)+10((−3)−1)
=−15+10(−4)
=−15−40
=−55
Hence, the value of the expression is -55.

Jessica and Laura are shopping for new clothes at a store that is going out of business. The different brands of shirts are all the same price, and the same goes for pants. At the store, Jessica purchases 3 shirts and 4 pairs of pants for a total of $90. Laura purchases 4 shirts and 2 pairs of pants for a total of $70.
Given Jessica and Laura's expenditure on shirts and pants, the equation to solve for the price of each shirts and pants is:
3s + 4p = 90
4s + 2p = 70
Let
Cost of each shirts = s
Cost of each pants = p
Jessica:
3s + 4p = 90 (1)
Laura:
4s + 2p = 70 (2)
Multiply (2) by 2
8s + 4p = 140 (3)
8s + 4p = 140 (3)3s + 4p = 90 (1)
Subtract (1) from (3) to eliminate p
8s - 3s = 140 - 90
5s = 50
s = 50/5
s = $10
substitute s = 10 into (1)
3s + 4p = 90 (1)
3(10) + 4p = 90
30 + 4p = 90
4p = 90 - 30
4p = 60
p = 60/4
p = $15
Therefore, the cost of each shirts is $10 and the cost of each pants is $15

Answer:
x = 5
Step-by-step explanation:
x is to x+5 what x-2 is 70 x+1
x/x+5 = x-2/x+1
x(x+1) = (x-2)(x+5)
x^2+x = x^2+ 5x - 2x - 10

The race is 123.90 meters long.
Since the next event requires each runner to jump 8 hurdles that are spaced 12.3 meters apart, if there are 15 meters from the starting line to the first hurdle and 10.5 meters from the last hurdle to the finish line, to determine how long is the race, the following calculation must be performed:
8 x 12.30 + 15 + 10.5 = X 98.4 + 25.5 = X 123.90 = X
Therefore, the race is 123.90 meters long.

The graph shows a system of equations: Draw a line labeled y equals x plus 4 by joining the ordered pairs negative 4, 0 and 1, 5. Draw a line labeled 3 times y equals minus 2 x plus 2 by joining the ordered pairs negative 2, 2 and 4, negative 2. What is the solution to the system of equations? a (−2, 2) b (2, 2) c (2, −2) d (−2, −2)
Answer:
A
Step-by-step explanation:
The problem wants you to solve graphically, but I don't have graph paper with me. To solve graphically, draw a straight line between the ordered pairs it gives and find the intersection. I will also solve algebraically; setting up our equations we get y=x+4 and 3y=-2x+2. By multiplying the first equation by 3, we can solve by elimination, resulting in 0=5x+10. After rearranging we have x=-2 and plugging back into y=x+4 gives y=2. Therefore our final answer is (-2,2) or A.

Ms. Smith has part of $1240 invested at 9% and the rest at 6.5%. If the annual
return from the two investments is the same, how much is invested at each
rate?
Answer:
Step-by-step explanation:
Let x be the amount invested at 9%.
Then the amount invested at 6.5% is 1240-x dollars.
From the condition, you have this equation
0.09x = 0.065*(1240-x).
x=520
