Hi there!
<u>Here is the step by step explanation into solving this :</u>
4 × (2² + 5)² ÷ 3 - 1
Start by solving the inside of the parentheses
2² = 2 × 2 = 4
4 + 5 = 9
Distribute the "²" to the whole parentheses
9² = 9 × 9 = 81
4 × 81 ÷ 3 - 1
Do the multiplication, then the division and lastly the subtraction
4 × 81 = 324
324 ÷ 3 = 108
108 - 1 = 107
The answer is : 107
There you go! I really hope this helped, if there's anything just let me know! :)
The answer is A
Five times a number
The first thing we must do for this case is to define a variable:
x: number of years
y: total salary
We have then:
For first company:
y = 1500x + 31000
For second company:
y = 2000x + 28500
Equaling both equations we have:
1500x + 31000 = 2000x + 28500
Clearing x:
2000x - 1500x = 31000 - 28500
500x = 2500
x = 2500/500
x = 5
Answer:
It will take for the salaries to be the same about:
x = 5 years
Step-by-step explanation:
Your problem → 5y+5/2 / 25y-20/40y^2-32y
5y+5/2÷25y-20/40y^2-32y
=5⋅y+5/2÷25×y-20/40×y^2-32×y
=5y+5/2÷25×y-20/40×y^2-32y
=5y+5/2×1/25×y-20/40×y^2-32y
=5y+y/10-20/40×y^2-32y
=5y+y/10-y^2/2-32y
=5y×10+y-y^2×5-32y×10 ÷ 10
=50y+y-5y2-320y ÷ 10
= -269y-5y^2 / 10
Answer:
-3
Step-by-step explanation:
Subtract 25x 125=-25x+50
Subtract 50 125-50= -25x
Simplify 75= -25x
Divided 75 by negatrive 25
