Answer: 4=X
Step-by-step explanation:
You divide 4x by itself, and divide 16 by 4x leaving you with X and 4 (I'm pretty sure)
Answer:
9 Is the answer.
Step-by-step explanation:
So you have to substitute these values in to the equation and solve.
3(-2) +5(11-8)
-6+5(3)
-6+15
9
Answer:
Yes
When comparing fractions such as 3/7 and 5/7, you could also convert the fractions
Answer:
x=12
Step-by-step explanation:
Before starting this question, you need to know that the total degree of any given triangle is 180 degrees.
Now looking at the question, we know one side is 90 degree since it is a right triangle.
180-90=90
This let us know that the remaining two angles will have to add up to equal to 90 degrees.
2x+1+5x+5=90
First, combine like terms.
7x+6=90
Now we have to get x by itself, subtract 6 on both sides then divide by 7.
7x=84
x=12
Answer: T=7
Step-by-step explanation:
0t−15−7.5t=6−0.5t
2 Simplify 10t-15-7.5t10t−15−7.5t to 2.5t-152.5t−15.
2.5t-15=6-0.5t2.5t−15=6−0.5t
3 Add 1515 to both sides.
2.5t=6-0.5t+152.5t=6−0.5t+15
4 Simplify 6-0.5t+156−0.5t+15 to -0.5t+21−0.5t+21.
2.5t=-0.5t+212.5t=−0.5t+21
5 Add 0.5t0.5t to both sides.
2.5t+0.5t=212.5t+0.5t=21
6 Simplify 2.5t+0.5t2.5t+0.5t to 3t3t.
3t=213t=21
7 Divide both sides by 33.
t=\frac{21}{3}t=
