Question 1. -3 + v5 = 0
Work : -3 + 5v = 0
5v = 3 ( divide )
answer v = 3/5
Question 2. 1 - 7B = -20
work : -7b = -20 - 1
-7b = -21 ( divide )
answer b = 3
question 3 : -k - 5 = 0
work : -k = 5
answer : k = - 5
Question 4 : -1 + 8a = 129
work : 8a = 129 + 1
8a = 130 (divide )
answer a = 65/4
Answer:
m=25w+80
Step-by-step explanation:
m=money
w=weeks
280-130=150
150/6=25 this is how much she earns per week
25*2=50 this is how much she earned in two weeks
130-50=80 this is how much she had before she worked
m=25w+80
plug in to check:
(25*2)+80=130
(25*8)+80=280
Answer:
3.25 - 1.75 = 1.50 pounds of flour
Step-by-step explanation:
Answer:
no
Step-by-step explanation:
Direct variation is of the form
y = kx
This has a constant added
y = kx+b so it is not a direct variation
Answer:
the desired equation is y = -5x + 2
Step-by-step explanation:
The general slope-intercept form is y = mx + b. Here we know that m = -5 and b = 2, so the desired equation is y = -5x + 2.
