Answer:
20
Step-by-step explanation:
simple 20(4)-15(4)=80-60=20
Answer: In 31 grams there are 0.031 kilograms.
Step-by-step explanation:
X + y = 10
y = x + 2
so sub in x + 2 for y back into the first equation
x + y = 10
x + x + 2 = 10
2x + 2 = 10
2x = 10 - 2
2x = 8
x = 8/2
x = 4
y = x + 2
y = 4 + 2
y = 6
solution is : (4,6)
When you want to find the value of a variable, isolate it.
First, add 355 to both sides of the equation to get rid of the -355 on the left side of the equation. We get -n = -602.
We're not done yet! We need to change the -n to +n, or just n. Multiply both sides by -1. We get n = 602.
n = 602.
Hope that helped you.
Answer:
35 and 70
Step-by-step explanation:
First I would start off by making a list of its multiples.
7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84.
Then find two (or more) of those numbers that can be divided evenly by 5.
35/5 = 7, so 35 works.
70/5 = 14, so 70 works.
