Answer:
15 1/6
Step-by-step explanation:
change -8 2/3 into an improper fraction = -26/3
-4/7v = -26/3
cross-multiply:
3(-4v) = (-26)7
-12v = -182
v = 182/12
v = 15 1/6

2x-y=60
6y=x
Solve the system using substitution. Check your solution.
Answer:
[tex]x = \frac{360}{11} [/tex]
[tex]y = \frac{60}{11} [/tex]
Step-by-step explanation:
Since 6y=x plug 6y in for x on the top equation.
[tex]2(6y) - y = 60[/tex]
[tex]12y - y = 60[/tex]
[tex]11y = 60[/tex]
[tex]y = \frac{60}{11} [/tex]
Plug y=60/11 into 6y=x
[tex]6( \frac{60}{11} ) = x[/tex]
[tex] \frac{360}{11} = x[/tex]
Plug 360/11 into 2x-y=60
[tex]2( \frac{360}{11} ) - \frac{60}{11} = 60[/tex]
[tex] \frac{720}{11} - \frac{60}{11} = 60[/tex]
[tex] \frac{660}{11} = 60[/tex]

1. There are 34 rose bushes currently in the park. Park workers will plant
more rose bushes today.
When the workers are finished there will be 70
rose bushes in the park. How many rose bushes did the workers plant
today?
34 + 70 = x; x = 104
34 - x = 70 ; x = 36
34 + x = 70; x = 36
70 - 34 = x; x= 36
Answer:
34 + x = 70 ; 36
Step-by-step explanation:
Given that:
Current amount = 34
Final amount = 70
Number of roses planted by the workers today ;
Current amount + number planted today = final amount
Let number planted today = x
34 + x = 70
x = 70 - 34
x = 36

What is the result when 12x2-7y2 is added by -10x2+y2?
A.2x2-6y2
B.2x2+6y2
C.-2x2-8y2
D.-2x2+8y2
Answer:
A
Step-by-step explanation:
12x² - 7y² - 10x² + y² = 12x² - 10x² - 7y² + y²
= (12 - 10)x² + (-7 + 1)y²
= 2x² + (-6y²)
= 2x² - 6y²

All lines that are parallel have the same slope
Answer:
the slope is (2)
Step-by-step explanation:
Two lines that are parallel to each other have the same slope so,
the equation y=2x+5 is in the form y=mx+c
where m is the slope of the line so if we compare both equations we can see that the slope of the line given will be 2 and therefore, the slope of the line parallel to it will be the same (2)
At the market, potatoes cost 1.15 per pound.Imagine you bought 3.45 worth of potatoes. How many pounds of potatoes did you buy? Explain a strategy you could use to solve this problem.

Which one of the following fractions is the largest?
5/6 1/3 3/2 5/2
Answer:
5/2
Step-by-step explanation:
Answer:
5/2 is the largest fraction.
Step-by-step explanation:
To find the largest fraction, we can convert some using the LCD (least common denominator)
Keep 5/6 as is.
1/3 = 2/6
3/2 = 9/6
5/2 = 15/6
So, 5/2 is the largest fraction.

if the velocity is big, must there be forces on it?
Answer:
Acceleration and velocity
Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force.

If the weight of 90 books is 50kg, what is the weight of 180 such books. In both proportion and unitary method.
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that the weight of 90 books is 50kg. We need to get the weight of a book first and this will be:
= 50/90
= 5/9
Therefore, the weight of 180 such books will be 5/9 multiplied by 180. This will be:
= 5/9 × 180
= 100kg
Factor: 3bc-4ad +6ac-2bd
Can you create a rubric for this math question
Answer:
(3c−2d)(2a+b)
Step-by-step explanation:
3bc−4ad+6ac−2bd
Do the grouping 3bc−4ad+6ac−2bd=(6ac−4ad)+(3bc−2bd), and factor out 2a in the first and b in the second group.
2a(3c−2d)+b(3c−2d)
Factor out common term 3c−2d by using distributive property.
(3c−2d)(2a+b)

How many 3-inch thick bags of mulch should Noemi buy to cover 100 square feet at a depth of 4 inches? The length is 3.2ft and the width is 2.5ft.
Answer:
Approximately 17 bags.
Step-by-step explanation:
The length of the bag of mulch = 3.2 ft
The width of the bag of mulch = 2.5 ft
The thickness of the bag of mulch = 3 inch = 0.25 ft
Volume of a bag of mulch = length x width x thickness
= 3.2 x 2.5 x 0.25
= 2 cubic feet
So that, the volume of a bag of mulch is 2 cubic feet.
The area to be covered = 100 square feet
The depth of the area = 4 inches = [tex]\frac{1}{3}[/tex] feet
volume of the portion to be covered = area x depth
= 100 x [tex]\frac{1}{3}[/tex]
= 33 [tex]\frac{1}{3}[/tex] cubic feet
The volume of the portion to be covered is 33 [tex]\frac{1}{3}[/tex] cubic feet.
The number of bags of mulch needed = [tex]\frac{33\frac{1}{3} }{2}[/tex]
= 16[tex]\frac{2}{3}[/tex]
= 16.6667
The number of bags of mulch needed is 17.
Find the value of r. I have no clue.
Answer:
12
Step-by-step explanation:
18 - 2r and 4r are the same length so the equation would be:
18 - 2r = 4r
Move the 2r to the other side
18 = 6r
Divide it by 6 to get r by itself
r = 3
