4x 75Step-by-step explanation:
Now I have never seen a question like this but it would make sense if the GCF is 5, 4x and 7 since 5 x 4x = 20x and 5 x 7= 35.
So the blank x would be 4 x, the right side would be 7 and the bottom left would be 5.

Answer:
Total square inches glass need = 432 inch square
Meter square paint need = 36.5 meter square
Step-by-step explanation:
Given:
Length of rectangular window = 24 inch
Width of rectangular window = 18 inch
Length of parallelogram = 7.3 meter
Height of parallelogram = 5 meter
Find:
1. Total square inches glass need
2. Meter square paint need
Computation:
Total square inches glass need = Area of rectangle window
Area of rectangle window = l x b
Area of rectangle window = 24 x 18
Area of rectangle window = 432 inch square
Total square inches glass need = 432 inch square
Meter square paint need = Area of parallelogram
Area of parallelogram = Base x Height
Area of parallelogram = 7.3 x 5
Area of parallelogram = 36.5 meter square
Meter square paint need = 36.5 meter square

Answer:
2/5
Step-by-step explanation:
5x+6y=11
as we have to find x coordinate
while y coordinate 3/2 is already given in question
so only put value of y coordinate in given equation to get x coordinate value
5x+6y=11
5x+6*(3/2)=11
5x+3*3=11
5x+9=11
5x=11-9
5x=2
x=2/5
3. There are 32 students in the school play. The ratio of girls to all students
in the play is 5: 8. How many girls are in the play?
4. Two out of three vehicles in a parking lot are SUVs. There are 18 SUVs
in the parking lot. How many vehicles are in the parking lot
Answers
Explanations
3- I believe the answer is 20
There are 32 students total and the ratio of girls to all of the students in the play is 5:8
So to get from 8 to 32 you need to multiply by 4, so you would go the same to the five which give you 20
The according to this, there are 20 girls in the play. And 20/32 = 62.5% as does 5/8
4- I believe the answer would be 27
As said, 2/3 of the vehicles are SUVs and that is equal to 18 SUVs.
To get what equals 1/3, you would divide 18 by two which gives you 9.
Now to get the total, you would have to multiply 9 by 3 to get all three parts which would give you 27

-3×4y = (4+5y)-72 answer fast with steps plz
Answers
Answer:
-12y=5y-68 true for all X
Step-by-step explanation:
-3x4y=(4+5y)-72
simplify:
-3x4y=12y
simplify:
(4+5y)-72
remove parentheses:
4+5y-72
subtract the numbers:
4-72= -68
=5y-68
-12y=5y-68
Answer:
the answer would be 4
Step-by-step explanation:
−3(4y)=4+5y−72
−12y=4+5y+−72
−12y=(5y)+(4+−72)(Combine Like Terms)
−12y=5y+−68
−12y=5y−68
Step 2: Subtract 5y from both sides.
−12y−5y = 5y−68−5y
−17y= −68
Step 3: Divide both sides by -17.
−17y -68
------------ = -----------
-17 -17
y = 4

66 baskets
Step-by-step explanation:
So, this is a simple math equation if you break it down step by step. Let's see what we know from the question.
First Day = Already 10 baskets.
Every day = +4 more baskets.
Meets her goal after 2 weeks/14 days
**Questions may use different units to try to trick you, such as weeks and days! But, they are the same.**
Okay, so now we have gathered the information we know, now lets make the math equation. First we need to make the variables. Let's let G equal how many baskets she made on day 14.
G = 10+(14x4)
G = 10+(56)
G = 66
So, she made 66 on the 14th day
