Margie would take 1 hour and 30 minutes to write 1 page of her research paper. Think of it like a proportion:
2.25/ 1.5 = x/1
2.25 is the 2 1/4 converted which is the amount of hours she took.
1.5 is the 1 1/2 converted which are the amount of pages she wrote total.
1 on the right side of the proportion represents 1 page.
And x are the amount of hours used to write 1 page.
And in solving that proportion it would result in 1.5 or 1hr. and 30 min.
Hello!
*I'm not very good at algebra, so I am not 100% sure this is correct!*
w = cost of washer
d = cost of dryer
w + d = $586
w = d - 64
d - 64 + d = 586
2d = 586 + 64
2d = 650
d = 650 / 2 = 325
586 - 325 = 261
Check 325 - 261 = 64
So, the dryer costs $325 and because the washer is $64 less than the dryer, it costs $261.
Answer:f(4)=−3x−1 f ( 4 ) = - 3 x - 1.
Step-by-step explanation:ff(4)=−3x−1 f ( 4 ) = - 3 x - 1.
f(4)=−3x−1 f ( 4 ) = - 3 x - 1. Replace the variable x x with 4 4 in the expression. f(4)=−3⋅4−1 f ( 4 ) = - 3 ⋅ 4 - 1. Simplify the result.
Answer:
B, D
Step-by-step explanation:
Any inequality that does not include the "or equal to" case will be graphed with a dashed line.
<h3>Application</h3>
The "or equal to" case is included when the inequality symbol is one of ≤ or ≥. When symbols > or < are used, the boundary line of the solution space is dashed (or the end point on the number line is an open circle).
The inequalities that will be graphed with a dashed line are ...
- 2x -4y < 12 . . . . choice B
- x +7 > -1 . . . . . . .choice D
Let's first define variables.
y: number of shares of $ 10
x: number of shares of $ 12
We write the system of equations:
10x + 12y = 210
y = 2x + 5
Solving the system:
x = 75/17
y = 235/17
Answer:
she has:
75/17 shares of $ 12
235/17 shares of $ 10
