First you can write it as 1.25 which it is the decimal version of the percent. Then write the 1.25x = 25. After divide both sides by 1.25. Ta da, You have your answer (which is 20).
Let's set these two numbers as 'a' and 'b'
Now, let's set up equations based on the information known:
- the sum of the two numbers is 52 --> a + b = 52
- the difference is 28 --> a - b =28
Equations
- a + b = 52 -- equation 1
- a - b = 28 -- equation 2
Solve:
(Equation 1) + (Equation 2)
2a = 80
a = 40 -- equation 3
(Equation 3)
40 + b = 52
b = 12
So a = 40 and b = 12
Hope that helps!
Answer:
(-14+3/2b) - (1+8/2b) goes with -15-5/2b
(5+26)+2b+3/2) goes with 4b+13/2
(-10+b)+(7b-5) goes with 8b-15
(7/2b-3)-(8+6b) goes with -5/2b-11
Step-by-step explanation:
Answer:
I cant really see the photo
3.5 times as much flour as chocolate chips....
f = 3.5c
f = 1 3/4 (or 1.75)
1.75 = 3.5c
1.75 / 3.5 = c
0.5 = c......chocolate chips needed would be 1/2 a cup
