Answer:
x=13
Step-by-step explanation:
We add all the numbers together, and all the variables
6x-78
We move all terms containing x to the left, and all other terms to the right
6x=78
x=78/6
which should equal 13
2(3-4a) + 5(a-7) first do the distributive property
6-8a + 5a-35 now combine like terms
-41 - 3a is the final answer
Step-by-step explanation:
“The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate.”
Answer:
769/70
Step-by-step explanation:
5 2/7 = 37/7
5 7/10 = 57/10
The lowest common multiple is 70
37*10/(7 * 10) = 370/70
57/10 = 57*7/(7*10) = 399/70
Now add
370/70 + 399/70
769/70
Is 769 prime? I think it might be.
Yes it is.
