Step-by-step explanation:
5 times c2+6 divided by 2 when c=2
First, get rid of c. 5 times 2 times 2+6 divided by 2
Then, multiply. 5 times 2 times2 +6 divided by 2
Now, we have 5 times 4+6 divided by 2
All we have to do now is go from left to right and solve!
5 times 4+6 divided by 2
20+6 divided by 2
26 divided by 2

Answer:
1. Percent 1: 30% Percent 2: 40%
Decimal: .3 Decimal: .4
Fraction: 3/10 Fraction: 4/5
Ratio: 30/100 Ratio: 40/100
2. You are finding the whole
Ways to solve
40% of 20 = 0.4 × 20 = 8 or
40% of 20 = 2/5 x 20 = 2/5 x 20/1 = 40/5
40/5
40/5 = 8/1
40% of 20 = 0.4 x 20 = 8.0
40% of 20=8.0
3. You are finding the part
4 divided by 5 equals=0.8 or
Percent : 30%
Decimal: .8
Fraction: 4/5
Ratio: 30/100

Answer:
(13)
x= 8
y=11
(14)
x= 20
y=20.75
(15)
x=9
y=13
Step-by-step explanation:
(13) 8x-1 = 11x -25
24=3x
x= 8
8(8)-1 +15y-48= 180
15y=165
y=11
(14) 7x-44 + 4x + 4= 180
11x= 220
x= 20
4(20)+4+39= 8y-43
123=8y-43
166=8y
y=20.75
(15) 12x+1=15x-26
3x=27
x=9
28+15(9)-26+4y-9=180
4y=52
y=13
