-15 is the answer of this
Step-by-step explanation:
Rules in Algebra
A hypothesis. A hypothesis is an educated guess, and the person is assuming that it rained.
Start with x+y=10 and x-y=4
Add the equations to eliminate y:
x+y=10
+ x-y=4
2x =14
So now solve for x:
2x=14 (Divide each side by 2 to get x by itself)
x=7
Now you have solved for x, but you still need to solve for y:
x+y=10
7+y=10 (Subtract 7 from both sides to get y by itself)
y=3
Now you have both x and y but to check it, just plug it into the original equations:
x+y=10 ----> 7+3=10 (That's correct)
x-y=4 ----> 7-3=4 (That's correct)
There's your final answer.
Answer:
38 1/2 meters
Step-by-step explanation:
You have to multiply 28× 1 3/8
You can convert yhe 1 3/8 to an improper fraction, then multiply, and convert back to a mixed number. See image.
OR,
you can distribute the 28 over the sum of 1 and 3/8. This just keeps the fraction a little bit smaller and you can practice distributive property see image
