Answer:
x = - 7 and y = 30
Step-by-step explanation:
2x - y = -9
subtract 2x from either side
-y = -9 - 2x
divide either side by -1
y = 9 + 2x
Plug in 9 + 2x for y
9 + 2x = -5 - 5x
Add 5 to either side and subtract 2x from either side
14 = -2x
divide either side by -2
-7 = x
plug in -7 for x in one of the equations
y = -5 - ( 5 x -7 )
y = -5 - ( - 35)
y = -5 + 35
y = 30
plug in x and y
30 = -5 - ( 5 x -7)
30 = -5 - (-35)
30 = -5 + 35
30 = 30
Answer:
B. −19
Step-by-step explanation:
Multiply both sides of the equation by y , and then isolate the variable.

−19
=
y
Divide both sides by 9

A=4ℼR2 solve for R
SHOW ALL STEPSSSSSSSSSSSSS
Given problem;
A = 4 π R²
To solve for R, we have to make it the subject of the expression.
Since
A = 4 π R² , follow these steps to find R;
Multiply both sides by [tex]\frac{1}{4\pi }[/tex]
A x [tex]\frac{1}{4\pi }[/tex] = [tex]\frac{1}{4\pi }[/tex] x 4 π R²
[tex]\frac{A}{4\pi }[/tex] = R²
Then find the square root of both sides
√R² = [tex]\sqrt{\frac{A}{4\pi } }[/tex]
R = [tex]\sqrt{\frac{A}{4\pi } }[/tex]
The solution is [tex]\sqrt{\frac{A}{4\pi } }[/tex]

Yesterday, Grace drove 36 1/2 miles. She used 1 1/4 gallons of gasoline. What is the unit rate for miles per gallon? The unit roto is miles per gallon?
Answer:
29.2 miles/gallon
Step-by-step explanation:
Given that,
Distance travelled, [tex]d=36\dfrac{1}{2}[/tex] miles
Grace used [tex]1\dfrac{1}{4}\ \text{gallons}[/tex] of gasoline
We need to find the unit rate for miles per gallon. It can be calculated by dividing no of miles by gallons of gasoline. So,
[tex]R=\dfrac{36\dfrac{1}{2}\ \text{miles}}{1\dfrac{1}{4}\ \text{gallon}}\\R=\dfrac{\dfrac{73}{2}}{\dfrac{5}{4}}\ \text{miles per gallon}\\\\R=\dfrac{73}{2}\times \dfrac{4}{5}\\\\R=29.2\ \text{miles per gallon}[/tex]
Hence, the unit rate is 29.2 miles/gallon.

Find y to the nearest hundredth place
Help pls due tomorrow
Answer:
B. 12.43 ft
Step-by-step explanation:
cosine = adjacent / hypotenuse
cos 43° = y / 17
multiply both sides by 17
17 (cos 43°) = y
cos 43° = 0.7314 (use your calculator)
y = 17 x 0.7314
y = 12.43 ft.

If the perimeter of the pink rectangle is 24 meters, what are its dimensions?
Answer:
You know the perimeter is 24 meters. this means that 24 is equal to 14 plus 2 times the width. since the perimeter is equal to 2 times the length plus 2 times the width, if you take away 2 times the length, you are left with 2 times the width. perimeter is equal to 24.
