Answer:
The most common benchmark percents are 0%, 10%, 25%, 50%, 75% and 100%.
To find 60% of 280 we first find 10% of 280 which is 28. 6 x 28 = 168.
To find 60% of 280 we first find 50% of 280 which is 140. Now we add 10% which we calculated before: 140 + 28 = 168.
Answer:
Step-by-step explanation:
Explain two ways you can benchmark percents to find 60% of 280
1) 280 : 100 * 60 = 168
2) 280 * 0.6 = 168

33% of what number is 1.45? Round to the nearest tenth.
Take the unknown number as 'y'.
=》33% = 33/100
=》1.45 = 145/100
33/100 × y = 1.45
33/100 × y = 145/100
33y = 145/100 × 100/1
33y = 145
y = 145/33
y = 4.39

There are 900 3-digit integers, the integers between 100 and 999, inclusive. What percent of these integers contain only odd digits
Each digit can be one of {1, 3, 5, 7, 9}, so there are 5 choices for each. Then there are 5•5•5 = 5³ = 125 integers containing only odd digits, which means they make of 125/900 ≈ 14% of them.

Answer:
cost of renting from company A
C = 15 + 2.30x
cost of renting from company B
C = 22 + 1.90x
equate both the equations
15 + 2.30x = 22 + 1.90x
2.30x - 1.90x = 22-15
0.4x = 7
x = 7/0.4 = 17.5
At 17.5 miles, cost will be equal.
Answer: 17.5 miles

Subtract from (4x- 5y+3z) from the sum of (9x+2y-3z), (-10x+ y- z) and (2x+ 3y+ 7z).
Explain
Step-by-step explanation:
★First let's find out the sum.
(9x + 2y - 3z) + (-10x + y - z) + (2x + 3y + 7z)
= (9x - 10x + 2x) + (2y + y + 3y) + (-3z - z + 7z)
= (x) + (6y) + (3z)
= x + 6y + 3z
★Now subtraction:
(x + 6y + 3z) - (4x - 5y + 3z)
= (x + 6y + 3z - 4x + 5y - 3z)
= (x - 4x + 6y + 5y + 3z - 3z)
= -3x + 11y★∴Answer is -3x + 11y

Step-by-step explanation:
a. Simply put (x+h) wherever you have x.
[tex]f(x+h) = -3(x+h)+7 = -3x +7 -3h[/tex]
b. We have the first part, just subtract
[tex]f(x+h) = -3(x+h)+7 = -3x +7 -3h - (-3x+7) = -3x+7-3h +3x -7 = -3h[/tex]
c. Finally, we divide by h[tex]\frac{-3h}h = -3[/tex]
