Answer:
x = 4
Step-by-step explanation:
Solve the inequality
2x - 3 > 11 - 5x ( add 5x to both sides )
7x - 3 > 11 ( add 3 to both sides )
7x > 14 ( divide both sides by 7 )
x > 2
The only value of x greater than 2 is 4, thus
x = 4 is in the solution set
Hello! The first thing you want to do is subtract 88 from 71 which gives you 17. If you multiply the belts times 71 that gives you 11,360. So then you have 17 left and all you do is multiply the shoe cost by 17 and that gives you 7,905. If you add 11,360+7,905 that gives you 19,265. So the correct answer would be 71!
I hope this helped!

Step-by-step explanation:
<u>Step 1: Define</u>
35 + 0.8x = 43 - 7x
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Addition Property of Equality] Add 7x on both sides: 35 + 7.8x = 43
- [Subtraction Property of Equality] Subtract 35 on both sides: 7.8x = 8
- [Division Property of Equality] Divide 7.8 on both sides: x = 1.02564
Answer:
9 and 21
Step-by-step explanation:
<u>setting up the equation</u>
let x and y represent the two numbers
this means that x + y = 30
x - y = 12
<u>using substitution to solve</u>
if x - y = 12, that can be rearranged to x = y + 12.
substitute x = y + 12 into x + y = 30
you get (y + 12) + y = 30
simplify
2y + 12 = 30
2y = 18
y = 9
plug this into the original equation x + y = 30. this would be
x + 9 = 30
x = 21
the numbers are 21 and 9.
A = 1000(1 + r)^t
A ?
R interest rate 0.06
T time 2 years
A=1,000×(1+0.06)^(2)
A=1,123.6 round your answer to get
1124 which is option c
