Answer:

Step-by-step explanation:

Formulas:
Area of a rectangle/square:


<u>Big Rectangles (2):</u>
7*3=21
Multiply by 2
21*2= 42 in
<u>Long rectangles (2)</u>
7*1=7
Multiply by 2
7*2= 14 in
<u>Short rectangles (2):</u>
3*1=3
Multiply by 2
3*2= 6 in
<u>Total: </u>
Add.
42+14+6= 62 in2
3x+8=5x-1
3x-5x=-1-8
-2x=-9
x=4,5
AM=3x4,5+8=21,5
MB=5x4,5-1=21,5
AB=AM+MB
AB=21,5+21,5=43
Answer:
C
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substituting values
=
( cross- multiply )
21x = 7(24 - x) ← distribute
21x = 168 - 7x ( add 7x to both sides )
28x = 168 ( divide both sides by 28 )
x = 6 → C
The chef can make 25 cakes
Explaintion:
There is a few ways to solve this but an app say way is to
Multiply the 15 gallons by the denominator of the fraction then divide by 3
So 15x5=75
75/3=25
Therefore the chef can make 25 cakes
I think it will be because if you multiply 1/2 times 4/5 it will be 0.4
