Answer:
y = 1 cm
x = 7 cm
Step-by-step explanation:
x = 3y + 4
perimeter = 2 * ( y + x ) = 16
x + y = 8 by using x = 3y + 4
y + 3y + 4 = 8
4y = 4
y = 1
1 + x = 8
x = 7
y = 1 cm
x = 7 cm

Jamal buys a new racing bicycle. Two shops charge the same price for the bicycle but offer different payment plans. Shop 1 requires $260 down and a monthly payment of $20. Shop 2 requires $140 down and a monthly payment of $30. Write an equation to represent the payment plans where m is the number of months payments are made.
Answer:
Shop 1 = $260 + $20m
Shop 2 = $140 + $30m
Step-by-step explanation:
m = number of months payments are made
Total payment made = down payment + monthly payment
Shop 1 requires $260 down and a monthly payment of $20.
Shop 1 = $260 + $20m
= 260 + 20m
Shop 2 requires $140 down and a monthly payment of $30.
Shop 2 = $140 + $30m
= 140 + 30m
The equations that represent the payments plans are:
Shop 1 = $260 + $20m
Shop 2 = $140 + $30m
URGENT !!!!!!!!!What is the value of x when the expression 3x + 6 equal the expression -15 + 6x WHat does x=__? BEST ANSWER FOR BRAINLYEST
Answer: x= 2
Step-by-step explanation:
hope this helped :)
Answer:
x=7
Step-by-step explanation:
well there's a simple way to do this, you out each side by side like so and solve:
3x+6=-15+6x
then you move like terms to the other side (like terms have the same variables). So we'll add 15 to both sides to balance the equation out because you cant remove a number from one side without affecting the other so:
3x+21=6x
then because we don't want an equation equal to 0 we move 3x to the other side by substracting 3x from both sides:
21=3x
now we divide by 3 both sides and because 21 divided by 3 is 7:
x=7

Solve: 3x -6/3 = x + 3/6
Answer:
x= 1/2
Step-by-step explanation:
start by adding 6/3 to both sides. the negative 6/3 on the left side will disappear, and the right side will equal one. (6/3 + 3/6= 9/9 = 1).
Youll end up with:
3x=x+1
now, subtract x from both sides to get:
2x=1
Divide both sides by two to get
x=1/2
If you had a triangle with side lengths of 2, 4, and 5, and
dilated it with a scale factor of 2.5, what would be the
side lengths of the resulting image?
Answer:
5,9,12.5
Step-by-step explanation:
After dilation, the final side lengths of the triangle become -
a' = 5 units, b' = 10 units, c' = 12.5 units
What is Dilation?A dilation is an enlargement or reduction of a figure about a center of dilation by a specified scale factor [k].
Given is a triangle with side lengths of 2, 4, and 5 and is dilated with a scale factor of 2.5
We have a triangle whose side lengths are -
a = 2 units
b = 4 units
c = 5 units
Scale factor = [k] = 2.5
Now, after dilation the final side lengths will become -
a' = 2.5a = 2.5 x 2 = 5 units
b' = 2.5b = 2.5 x 4 = 10 units
c' = 2.5c = 2.5 x 5 = 12.5 units
Therefore, after dilation, the final side lengths of the triangle become -
a' = 5 units, b' = 10 units, c' = 12.5 units

Complete Question
A veterinarian is vaccinating cattle. One bottle of vaccine is 8 ounces.
a) How many 2/3 -ounce doses can the veterinarian get out of one bottle of vaccine?
b) How many ounces of vaccine will be left in the bottle after she draws the maximum number of doses out?
Answer:
a) 5 1/3 ounces or 5.3333333333 ounces
b) 2 2/3 ounces or 2.67 ounces
Step-by-step explanation:
a) How many 2/3 -ounce doses can the veterinarian get out of one bottle of vaccine?
This is calculated as:
2/3 ounces of 1 bottle
2/3 ounces of 8 ounces
= 16/3 ounces
= 5 1/3 ounces or 5.3333333333 ounces
b) How many ounces of vaccine will be left in the bottle after she draws the maximum number of doses out?
This is calculated as:
8 ounces - 5 1/3
= 2 2/3 or 2.67 ounces

Ferdie was having a big party and he was excited. He had been practicing his opening lines all week and as soon as he he got to the part, 20 girls at the party left. There now remained 2 boys for each girl. A lot of the other boys thought the party was pathetic, so 20 of the boys also left. There were now 3 times as many girls as boys. How many boys and girls were at the party when Ferdie got there?
Answer: Boys = 24
Girls = 32
Step-by-step explanation:
Let the original number of boys = b
Let the original number of girls = g
The following can be further gotten from the question:
When 20 girls left, the equation can be written as:
b = 2(g - 20)
b = 2g - 40 ........ equation i
When 20 boys left, the equation can be written as:
(g-20) = 3(b-20) ......... equation ii
Substitute the value of b into equation ii and solve.
(g-20) = 3(b-20)
g - 20 = 3(2g - 40 - 20)
g - 20 = 3(2g - 60)
g - 20 = 6g - 180
6g - g = 180 - 20
5g = 160
g = 160/5
g = 32
Therefore, the original number of girls = 32.
The original number of boys will be:
b = 2g - 40
b = 2(32) - 40
= 64 - 40
= 24
