Answer:
a) 3x - 11
b) 10x + 4
Step-by-step explanation:
a) The negative sign before the (x+5) means to subtract those values. Reverse the signs. Then combine like terms:
4x –6 –x –5. 4x–x–6–5
3x –11
b) Put all the x terms together.
Put all the integers together.
Add. Adding a negative is the same as subtracting.
4x+x+5x = 10x
+6-2 = 4
Combine them:
10x + 4
Answer:
1/3
Step-by-step explanation:
sum of numbers = 30 marbles
probability = 10/30 or simplified 1/3
50.25% off because 100÷199=50.25
The answer is C. 55
You get your answer by adding together the degrees of the angles you know 55+70
That equals 125 degrees and subtract that from 180 degrees
180-125= 55
Knowing the ratio for dogs to cats is 10:9
To get to 50 dogs they multiplied 10x5
So multiply 9x5 as well to get the number of cats
Cats = 45
