Answer:
a parallelogram is a rectangle so the sides are 3cm and the other two are 7cm
Step-by-step explanation:
how to calculate the area is u multiply 7 by three and there is your answer
4x−5=7+4y
subtract 7 from both side
4x - 5 -7 = 4y
4x -12 = 4y
divide by 4
4x/4 -12/4 = 4y/4
x-3=y
X=7
Hope this helps and have a wonderful day!
Do you have a picture?? Maybe? I’m not good at these
The ratio is:
Chlorine : Water = 1 : 10
m ( Water ) = 15 ounces
m ( Chlorine ) = x
x : 15 = 1 : 10
10 x = 15 * 1
10 x = 15
x = 15 : 10
x = 1.5 ounces
Answer:
We need to add 1.5 ounces of Chlorine for the correct ratio.
