−16=−4(2x−8) please help
Answer:
x = 6
Step-by-step explanation:
−16=−4(2x−8)
Let's rearrange so solving would be easier.
-4(2x-8) = -16
Let's open the brackets. Please take note of the signs (+) (-).
(-4 * 2x) + (-4 * -8) = -16
-8x + 32 = -16
Subtract 32 from both sides. Please take note of the signs (+) (-).
-8x + 32 (-32) = -16 (-32)
-8x + 0 = = -48
-8x = -48
Divide both sides by -8.
-8x/-8 = -48/-8
x = 6

Step-by-step explanation:
Jasmine is thinking about buying a car and is comparing two vehicles. One gets 13 miles to the gallon (mpg) and the other agents 26 miles to the gallon. Assuming that she drives 5,000 miles a year, how much money would she save by buying the more fuel efficient car if gas is $3 a gallon?
Answer:
$576.93
Step-by-step explanation:
Car A
13 miles to the gallon (mpg)
13 miles = 1 gallon
Car B
26 miles to the gallon
26 miles = 1 gallon
Car B is more fuel efficient than car A
1 gallon = $3
Assuming that she drives 5,000 miles a year
Cost of buying Car A
5000 miles / 13 miles × $3
= 384.62 × 3
= $1,153.86
Cost of buying car B
5000 miles / 26 miles × $3
= 192.31 × 3
= $576.93
Car A - car B
= $1,153.86 - $576.93
= $576.93
Jasmine will save $576.93 by buying the more fuel efficient car if gas is $3 per gallon
If g(x) = x^2 + 7, find g(-3)
Answer:
g(-3) = 16
Step-by-step explanation:
Simply substitute x as -3 to find your answer:
g(-3) = (-3)² + 7
g(-3) = 9 + 7
g(-3) = 16

If John pays $144 for 9 pounds of pears, how much is each pound
Answer:
$16 per pound
Step-by-step explanation:
We want to find the price per pound.
Therefore, we must divide the cost by the pounds.
[tex]\frac{cost}{pounds}[/tex]
We know it costs $144 for 9 pounds of pears. Therefore, $144 is the cost and there are 9 pounds.
[tex]\frac{\$144}{9 pounds}[/tex]
Divide.
[tex]\$16 /pound[/tex]
It costs $16 for each pound of pears.

The temperature was 80 C. Then the temperature fell 90 C. What was the temperature after it fell?
Answer:
-10 °C
Step-by-step explanation:
Subtract 90 from 80, since it dropped that much:
80 - 90
= -10
So, the temperature after it fell was -10 °C
Answer: -10 Celcius
Step-by-step explanation:
The tempature was 80 degrees and dropped by ninety, and since it dropped then you must subtract. 80 - 90 is -10 degrees Celcius. The temperature is -10 Celcius.

if LM=3x-9 and MN=x+1, find LN
Answer:
LN=12
Step-by-step explanation:
3x-9=x+1 add 9 to both sides
3x=x+10 subtract 1x on both sides
2x=10 divide by 2
x=5
3(5)=15-9=6
5+1=6
6+6=12

Find the area of the rectangle.
2x + 4
4x - 2
Answer:
8x² + 12x – 8
Step-by-step explanation:
From the question given above, the following were obtained:
Length (L) = 2x + 4
Breadth (B) = 4x – 2
Area (A) =..?
The area of a rectangle is given by:
Area (A) = Length (L) × Breadth (B)
A = L × B
Thus with the above formula, we can obtain the area of the rectangle as follow:
Length (L) = 2x + 4
Breadth (B) = 4x – 2
Area (A) =..?
A = L × B
A = (2x + 4) (4x – 2)
Expand
A = 2x(4x – 2) + 4(4x – 2)
A = 8x² – 4x + 16x – 8
A = 8x² + 12x – 8
Therefore, the area of the rectangle is 8x² + 12x – 8
