Answer:
1
Step-by-step explanation:
This shows how to multiply fractions. When you multiply fractions, you just multiply across, and then simplify.
sweater = s, blouse = b
s + b = 57, s = 2b
2b + b = 57, 3b = 57, b = 19.
s = 2b = 2(19) = 38.
sweater costs 38 dollars, and blouse costs 19 dollars
M = 7 is the given slope
(x,y) = (-4,-3) is the given point
Turn to slope-intercept form and use these values to find b
y = mx+b
-3 = 7(-4)+b ... plug in the given values
-3 = -28+b
-3+28 = -28+b+28
25 = b
b = 25
since we know that m = 7 and b = 25, the equation y = mx+b turns into y = 7x+25
The final answer is choice A
Answer:
18 + x or x + 18
Step-by-step explanation:
Hi there! I'm glad I was able to help you solve this math problem!
We are already given the number eighteen to start with, so this helps us a lot.
Since the word INCREASED means to add, and <u>we're increasing eighteen by x</u>, all you have to do is write it out to get your algebraic expression, as shown:
18 + x
You can also write the expression as x + 18! It doesn't matter what order you write it in.
I hope this helped you! You can comment below if you have any further questions! :)
Step-by-step explanation:
-7(y-1)= 21
-7y+7=21
-7y=21-7
-7y=14
divide by-7
y=-2
