Answer:
1. 78%
2. 16
Step-by-step explanation:
35 + 10 = 45
Danny got 35/45 answers correct.
Divide 35 into 45
35 ÷ 45 = .777777778
.777777778 ≈ .78
To convert a decimal to a percentage, move the decimal point two spaces behind.
.78 = 78%
Danny got 78% of the answers correct.
80% = .8 = ![\frac{8}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B10%7D)
Multiply
by 20 to get the answer
×
= ![\frac{160}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B160%7D%7B10%7D)
Simplify
= 16
Answer:
The two numbers would be 57 and 58.
Step-by-step explanation:
You can solve this problem using algebra. Use x to represent the smaller number and x + 1 to represent the greater number. You use x + 1 to represent the larger number because it is 1 more than the smaller number.
x + (x + 1) = 115
2x + 1 = 115
2x = 114
x = 57
Therefore, the numbers are 57 and 58. You can plug 57 into x + 1 to find the larger number.

I really hope this help
-2=-(x-8)
-2=-x + 8
-10= -x
x = 10
