Use the property of substitution to solve:
2 ( x - 2y = 15) ... 2x - 4y = 30
2x + 4y = -18
subtract..... 4x = 12
divide by 4 x =3 place into original equation 3 - 2y = 15
-2y = 12
y = -6
(3, -6)
So since xd is 5 that means ad is 10
now you have 2 sides all you need is to find the last side you can use Pythagorean theorem and get 26 for db
answer 26.
Answer:
1/30
Step-by-step explanation:
25/30 - 24/30
25-24/30
= 1/30
4.3245 g/cm^3.
V= MD
V= 4.35(0.93)
Answer:
Step-by-step explanation:
Let m represent the number of miles that she drives per day.
She works 5 days per week. This means that the total number of miles that she drives in a week would be
5 × m = 5m
Ms.Franks drives a maximum of 150 miles per week to and from work. Therefore, the inequality that shows m the number of miles she drives per day would be
5m ≤ 150
m ≤ 150/5
m ≤ 30
