Step-by-step explanation:
m > n <em>add 2.1 to both sides</em>
m + 2.1 > n + 2.1 TRUE
m > n <em>subtract (-4) from both sides</em>
m - (-4) > n - (-4) TRUE
m > n <em>add 16.5 to both sides</em>
16.5 + m > 16.5 + n TRUE
m > n → 3 + m > n <em>logic</em>
3 + m > n <em>add 6 to both sides</em>
9 + m > 6 + n TRUE
Answer:
x +5
Step-by-step explanation:
x² + 10x + 25 = x² + 5x + 5x + 5*5
= x(x + 5) + 5(x + 5)
= (x + 5) (x +5)
Find the reciprocal of 3/5 (by flipping the fraction)
5/3
Multiply 5/3 by 3/4
3/4(5/3)= 15/12= 1 1/4
Martina can walk 1 1/4 miles in one hour.
Hope this helps!
Answer:
- x = 37 1/2
- x = 2
Step-by-step explanation:
Parallel lines divide transversals proportionally. I like to write the proportions so the variable is in the numerator. Then the solution is obtained by multiplying by the denominator of the variable term.
1. x/20 = (46 -16)/16
x = 20(30/16)
x = 37.5
__
2. (x +4)/13.5 = 4/9
x +4 = 13.5(4/9) = 6
x = 6 -4
x = 2
400
Explanation:
1/3 of 600 is 200. That represents the boys.
Subtract 200 from 600, you get 400. That represents everybody else in the sample size (in this case, girls).
