Answer:
-8
Step-by-step explanation:
r=2
so multiply third term by 2
Using the commutative property means that you could do 5x4=20 and flip it around so it’s 4X5 the answer would still be 20 but in a different order
Answer:
One fourth is the same as dividing one whole into four equal fourths. Similarly, dividing 12 by 4 is the same as dividing one whole 12 into fourths.
Use sohcahtoa. tan64= x/7 x= 14.4

Given :7x+6=5(x+2)
Now We will use the distributive property to multiply 5 by x+2.
→7x+6=5x+10
We will Subtract 5x from both sides.
→7x+6−5x=10
We will Combine 7x and −5x to get 2x.
→2x+6=10
We will Subtract 6 from both sides.
2x=10−6
We will Subtract 6 from 10 to get 4.
2x=4
We will Divide both sides by 2.
x= 4/2
At last,We Divide 4 by 2 to get 2.
x=2
