There are 8 parts in total by adding the ratio. Math 2/8×2.4=0.6 hr
Eng. 2/8×2.4=0.6 hr
Hist. 3/8×2.4=0.9hr
Social. 1/8×2.4=0.3 hr. Add them all will get 2.4
I’m not sure I understand the question
Y = 12% = 0.12
y = 100(0.05) + x(0.2) / 100 + x
0.12 = 5 + 0.2x / 100 + x
0.12( 100 + x ) = 5 + 0.2x
12 + 0.12x = 5 + 0.2x
7 = 0.08x
x = 87.5
hope this help
Answer:
20
Step-by-step explanation:
You use the distributive property.
Distribute the 2 to whatever is inside the parentheses. (You will multiply)
4×2=8
2×6=12
Substitute the answers above into the parentheses.
(8+12)=20
The answer would be twelve 12 because 6x.5 is 3 and 3+9 is equal to 12
