Answer:
x= 4
Step-by-step explanation:
3x + 7 = 5x - 1
combine the like numbers: add 1 to the other side, isolating 5x
3x + 8 = 5x
Subtract 3x from 5x, isolating 8
8 = 2x
divide
4 = x
Check if it works
3(4) + 7 = 5(4) - 1

On Saturday, Kylee’s volleyball team will be having a family picnic. Hot dogs are sold at the local store with 15 hot dogs in a package. Hot dog buns, however, are only sold in packages of 6 hot dog buns. Kylee’s team wants to buy the exact same number of packages for hot dogs as hot dog buns.
What is the least number of packages of hot dogs and hot dog buns that Kylee’s team should buy to have exactly the same number of hot dogs as hot dog buns? If a package of hot dogs cost $2.98 and a package of hot dog buns cost $2.16, what was the total expense?
Answer:
Kylee's family need at least 2 packages of hot dogs and 5 packages of hot dog buns to have exactly the same number of hot dogs and hot dog buns.
Total expense is $16.76
Step-by-step explanation:
The lowest common multiple of 6 and 15 is 30.
Two packages of hot dogs contain 30 hotdogs.
Five packages of hot dog buns contain 30 hotdog buns.
If one package of hotdog costs $2.98, two packages would cost $2.98 × 2 = $5.96
If one package of hot dog buns costs $2.16, five packages would cost $2.16 × 5 = $10.8
$5.96 + $10.8 = $16.76
Susan buys the items listed below at a grocery store. 2 packages of chicken priced at $12.56 per package 1 pound of broccoli priced at $1.98 per pound 2 1 gallon of milk priced at per $3.49 gallon There is no sales tax on the food she buys. Susan pays for the items and receives $0.80 in change. What amount of money does Susan use to pay for the items?
Answer: $30
Step-by-step explanation:
Your question isn't well written. Here's the complete question:
Susan buys the item listed below at a grocery store. 2 packages of chicken priced at $12.36 per package. 1/2 pound of broccoli priced at $1.98 per pound. 1gallon of milk priced at $3.49 per gallon. There is no sales tax on the food she buys. Susan pays for the items and recevies $0.80 in change. What amount of money does Susan use to pay for the items?
2 packages of chicken priced at $12.36 per package will cost:
= 2 × $12.36
= $24.72
1/2 pound of broccoli priced at $1.98 per pound will cost:
= 1/2 × $1.98
= $0.99
1 gallon of milk priced at per $3.49 per gallon will be:
= 1 × $3.49
= $3.49
We are then told that Susan pays for the items and receives $0.80 in change. The amount of money does Susan use to pay for the item will be:
= $24.72 + $0.99 + $3.49 + $0.80
= $30
Find the value of xxx in the triangle shown below.
Answer:
x = 50 °
Step-by-step explanation:
This is an isosceles triangle, and this is apparent because there are two sides which are of the same length (7). This means that the angles opposite to it would also be same (this is one of the properties of an isosceles triangle).
So the other angle would also be x. And the sum of all angles in a triangle would add up to 180.
x + x + 80 = 180
2x = 100
x = 50 °

A class of 80 girls and 60 boys sponsored a car
wash. If 40 percent of the girls and 30 percent of
the boys got their cars washed, approximately
what percent of the class got their cars washed?
O A. 91%
OB. 64%
OC. 50%
OD. 36%
Answer:
D
Step-by-step explanation:
80/100 x 40 = 32
60/100 x 30 = 18
18 + 32 = 50
50/(80+60) x 100 = 35.7
= 36
Thank you
Answer:
36%
Step-by-step explanation:
class total: 140 students
40% of 80= 32
30% of 60=18
18+32= 50
50 divided by 140= .36 or 36 percent

the graph shows the functions
Answer:
x = -1, y = -1 and x = [tex]\frac{1}{2}[/tex] , y = 2
Step-by-step explanation:
To find the solution of the system of equations from their graphs find the intersection points between the two graphs, they are the solution of the system
In the given figure
∵ f(x) = 2x + 1
∴ It is represented graphically by a line
∵ g(x) = [tex]\frac{1}{x}[/tex]
∴ It is represented graphically by two curved lines on 1st and 3rd
quadrants
∵ The solution of the system of the equations is the points of
the intersection of the two graphs
∵ The two graphs intersected at points (-1, -1) and ([tex]\frac{1}{2}[/tex] , 2)
∴ The solution of the system of the equations is (-1, -1) and ([tex]\frac{1}{2}[/tex] , 2)
∴ x = -1, y = -1 and x = [tex]\frac{1}{2}[/tex] , y = 2

please help!! 20 points
Answer:
x = y = 36°
Step-by-step explanation:
Inscribed angles subtended on the same arc are congruent.
The measure of the inscribed angle is half the measure of its intercepted arc, thus
x = y = 0.5 × 72° = 36°
The cost of a pizza varies directly as the square of its radius. If a pizza with a 6 inch radius costs Php 8.00, how much should a pizza with an 11 inch radius cost?
Answer:
An 11 inch radius pizza costs Php 14.63!
Step-by-step explanation:
We have to find the average cost for each inch radius of pizza!
8/6 = 1 1/3
The average cost is Php 1.33
Now we multiply that by 11
1.33 * 11 = 14.63
An 11 inch radius pizza costs Php 14.63
A pizza with a 6 inch radius costs Php 8.00.
A pizza with 11" radius costs Php 26.88.
Let:-
k = constant
c = cost of a pizza
r = radius of pizza
The cost of a pizza varies directly as the square of its radius.
[tex]c[/tex] ∝ [tex]r^{2}[/tex]
[tex]c=kr^{2}[/tex]
Where: c = 8, r = 6
[tex]8=k(6)^{2} \\k=\frac{8}{36} \\\\k=\frac{2}{9}[/tex]
When r = 11 inch
[tex]c=kr^{2}\\c=(\frac{2}{9})(11)^{2}\\c=26.88[/tex]
Therefore, A pizza with 11" radius costs Php 26.88.
