Answer:
x = -6
Step-by-step explanation:
expand the brackets:
7x+28 + 6x-18 = 8x-24 - 2x-8
now, collect like terms:
13x + 10 = 6x -32 (subtract 6x from both sides)
7x + 10 = -32 (minus 10 from both sides)
7x = -42 (divide by 7)
x = -6

Step-by-step explanation:
Answer: Magnum = $2.10
Paddlepop = $1.20
<u>Step-by-step explanation:</u>
Let M represent Magnum and P represent Paddlepop, then create a system of equations using the cost as one equation and the difference in price as the other. Use the elimination method to solve for one of the variables and substitution to solve for the other.
3M + 2P = 8.70 → 1(3M + 2P = 8.70) → 3M + 2P = 8.70
M - P = 0.90 → 2(M - P = 0.90) → <u>2M - 2P = 1.80 </u>
5M = 10.50
M = 2.10
M - P = 0.90
2.10 - P = 0.90
-P = -1.20
P = 1.20
0.2 if 1 Mile is 5 Minutes then every 0.1 mile is 30 seconds so 1 minute would be 0.2
Answer:
The sear tower is 
times higher than the sears tower model
Step-by-step explanation:
we know that
The ratio of the height of the model to the height of the actual sears tower is equal to the scale factor
Let
z------> the scale factor
x-------> the height of the model
y-------> the height of the actual
so
we have
substitute
simplify
Remember that
so
