1 and 1/3 miles is how long
Answer:
n=-8
Step-by-step explanation:
Solve by isolating the variable by using the properties of equalities.
First, divide both sides by -6,
Then, subtract 1 from both sides,
This is the quickest method of solving the equation. However, it is also possible to solve by distributing the -6 in the beginning and then solving.
Answer:
Step-by-step explanation:
This question is a bit more up to you. The paint has to be a green that is more yellow, so as long as you add more yellow than blue, your answer should be correct! For example 3 cups of yellow to 1 cup of Blue, or 3.3 yellow to 2 cups of blue
1. -4a-6=-12
add 6 to both sides
-4a-6+6=-12+6
-4a=-6
Divide by -4
2.
add
to both sides but you will need to make a common denominator on the right
Divide by
which means multiply by the <span>reciprocal</span>.
3.

Subtract
Divide
4. 3w+7=20
Subtract
3w=13
Divide
5. -.2p+.4=-1.2
Subtract
-.2p=-1.6
Divide
p=8
6.
Add, made sure you change to common denominator first
Multiply by 4
y=5
Hope that helps
Answer:
to the 2nd power equals
Step-by-step explanation:
Let the unknown number which is raised to 2nd power be =
So, the expression can be written as:
Solving for
Taking square root both sides to remove the 2nd power.
Since 9 and 16 are perfect square, we can write them in 2nd powers of 3 and 4 respectively.
∴
