Answer:
28 is 10% of 280
Steps to solve "28 is 10 percent of what number?"
We have, 10% × x = 28
or,
10
100
× x = 28
Multiplying both sides by 100 and dividing both sides by 10,
we have x = 28 ×
100
10
x = 280
If you are using a calculator, simply enter 28×100÷10, which will give you the answer.

{6x+5y=4
{6x-7y=-20
solve by elimination
Answer:
x = -1, y = 2
Step-by-step explanation:
6x + 5y = 4
6x - 7y = -20
We already have a similar leading coefficient (6 for X), so we just subtract equation 1 from equation 2 to get:
12y = 24
Now solve normally:
y = 2
Then substitute into the first equation (or second, it doesn't matter)
6x + 10 = 4
6x = -6
x = -1

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:
Answer:
t = 2.9t= 2 9/10Step-by-step explanation:
t + 9.35 = 12 1/4
t + 9.35 = 12.25
t = 12.25 - 9.35
t = 2.9(2.9) + 9.35 = 12 1/4
12.25=12 1/4
12 1/4 = 12 1/4

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]
What is the measure of angle 1
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.
а (b) Two ovens are used to bake banana cakes and chocolate cakes. Each oven will ding according to its setting time. A banana cake takes 50 minutes to bake wbile a chocolate cake takes 45 minutes to bake.
(i) If each cake is put into the ovens at the same time, what is the time taken until both ovens ding simultaneously?
(ii) When the both ovens ding, how many banana cakes and chocolate cakes are baked?
Answer:
(b)(i) LCM of 45 and 50 = 450
Hence, it take 450 minutes until both ovens ding simultaneously.
(b)(ii) 450÷50=9 banana cakes baked
450÷45=10 chocolate cakes baked.

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
