Answer:
y = -3.3 then -7.1
y = -7.1 then -10.9
y = -2.6 then -6.4
y = 1 then -2.8
y = 4.2 then 0.4
Step-by-step explanation:
(-3.8)+0+y can be simplified to -3.8 + y. Evaluate each value for y by substituting it into the expression and solving.
y = -3.3 then -3.8 + -3.3 = -7.1
y = -7.1 then -3.8 + -7.1 = -10.9
y = -2.6 then -3.8 + -2.6 = -6.4
y = 1 then -3.8 + 1 = -2.8
y = 4.2 then -3.8 + 4.2 = 0.4
Answer:
R7,200
Step-by-step explanation:
We find the new salary by multiplying the old salary by 20% and adding this value to the old salary.
Thus, we have 6,000 + (6,000 * 0.20) = 6,000 + 1,200 = R7,200
Answer:
Step-by-step explanation:
Given
--- Average
--- Average
Required
Determine the overall average
Represent the sum of the first three with x.
So:
Solve for x
Represent the sum of the next seven with y.
So:
Solve for y
The overall average is calculated as thus:
Answer:
-8-x or -x-8 or x=-8
Step-by-step explanation:
Distribute the -8 to the (1+x)
-8-8x+7x
then add the -8x+7x
-8-x or -x-8
and if you want to solve for x
x=-8
