Answer:
3/5 y +9/10 z
Step-by-step explanation:
4/5 y + 7/10 z - 1/5 y + 1/5 z
4/5 y - 1/5 y + 7/10 z + 1/5 z
We need to get a common denominator for the z term of 10
4/5 y - 1/5 y + 7/10 z + 1/5 *2/2 z
4/5 y - 1/5 y + 7/10 z + 2/10 z
3/5 y +9/10 z
Answer:
O.13
Step-by-step explanation:
to find it in decimal form, you divide the percent by 100, because percents are out of 100. so 13% is 13/100 and when you divide it you get 0.13
Since -1 is less than or equal to -1 you input it into the first equation.
-3•(-1) -4
3-4
-1
the answer is -1 good luck
