4 1/2 = 18/4
3 3/4 = 15/4
15/4 + 18/4 = 8 1/4 or 33/4
33/4 * 1.6/1 = 52.8/4 = 13.2
When assuming 1 mile equals 1.6 kilometers, Suzanne ran 13.2 kilometers in all.
Answer: 2175
Step-by-step explanation: 25 x 87
height times width
Answer:
x=5
Step-by-step explanation:
9x^2 - 2x + 25 = 8x^2 + 8x
9x^2-8x^2-2x-8x+25=0
x^2-6x+25=0 factorize
(x-5)(x-5)=0
x-5=0 then x=5
Answer:
A
Step-by-step explanation:
Given the 2 equations
2x + y = 13 → (1)
x - y = - 4 → (2)
Add the 2 equations term by term to eliminate the y- term, that is
3x = 9 ( divide both sides by 3 )
x = 3
Substitute x = 3 into either of the 2 equations and solve for y
Substituting into (1)
2(3) + y = 13
6 + y = 13 ( subtract 6 from both sides )
y = 7
solution is (3, 7 ) → A
Answer: 1:6 or 1/6
Step-by-step explanation: there are 6 possible numbers you could roll on a fair die, so rolling a three would be 1:6
