Answer:
X=-4, y=-7
Step-by-step explanation:
6x-5y=11. 1st equation
y=7x+21 2nd equation
6x-5(7x+21)=11. Sub value of y in 2nd equation (7x+22) into 1st equation
6x-35x-105=11. Solve by distributative property
-29x-105=11. Add x values
-29x=116. add 105 to both sides
x=-4. Solve for x
solve for y:
y=7x+21
y=7(-4)+21
y=-28+21
y=-7
check answer by substituting x and y into either equation
6x-5y=11
6(-4)-5(-7)=11
-24+35=11
11=11
Answer:
A. 40 mph
Step-by-step explanation:
A bird flies 2/3 miles per minute. You are trying to solve miles per hour.
Note that there are 60 minutes in an hour. Multiply 2/3 with 60:
2/3 x 60 = (2 * 60)/3 = (120)/3 = 40
A. 40 mph is your answer.

Answer:
$6,106.87
Step-by-step explanation:
The total of percentage deductions is ...
state tax + city tax + social security + medicare
= 3.5% +2.5% +6.2% +1.45% = 13.65%
Then Ryleigh's take-home pay is ...
gross(1 -13.65%) -112 = 5161.28
gross = (5161.28 +112)/0.8635 = 6106.87
Ryleigh's monthly gross is $6,106.87.
Hello!
As you can see, our distance is the product of our rate and time. Let's multiply below.
32(4.5)=144
Therefore, you would have traveled 144 miles.
I hope this helps!
