0.6(x + 2) = 0.55(2x + 3)
Answer:
-0.9
Step-by-step explanation:
0.6(x+2)=0.55(2x+3)
Use the distributive property to multiply 0.6 by x+2.
0.6x+1.2=0.55(2x+3)
Use the distributive property to multiply 0.55 by 2x+3.
0.6x+1.2=1.1x+1.65
Subtract 1.1x from both sides.
0.6x+1.2−1.1x=1.65
Combine 0.6x and −1.1x to get −0.5x.
−0.5x+1.2=1.65
Subtract 1.2 from both sides.
−0.5x=1.65−1.2
Subtract 1.2 from 1.65 to get 0.45.
−0.5x=0.45
Divide both sides by −0.5.
x= 0.45/−0.5
x= -0.9
xoxo,your highness...What is the slope of the line that passes through the points (-8,-3)and(-12,-3) write your answer in the simplest form
Answer:
[tex]m=0[/tex]
Step-by-step explanation:
Given the points
(-8,-3)and(-12,-3)
The slope between the points (-8,-3) and (-12,-3) can be determined
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-8,\:-3\right),\:\left(x_2,\:y_2\right)=\left(-12,\:-3\right)[/tex]
[tex]m=\frac{-3-\left(-3\right)}{-12-\left(-8\right)}[/tex]
[tex]m=0[/tex]
what is 20+.25g=22
need step by step explanation
Answer:
g = 8
Step-by-step explanation:
first move 20 to the right side of the equation by subtracting it. so the equation becomes 0.25g= 22-20 --> 0.25 = 2 and then divide 2 by 0.25 and g will equal 8. you can also plug in 8 for g to check your answer.
Answer:
g = 8
Step-by-step explanation:
First we want to simplify the sides so we will subtract 20 fror each side
.25g =2
then we need to divide each side by .25 to get g isolated or by itself to find the answer
g = 8
If you plug it back into the equation it will be true
20 + (.25 * 8) = 22
⦁ A local pizzeria sold 75 pizzas yesterday.
⦁ The owner offers the employees a bonus if the number of pizzas sold increases by 20% today.
⦁ How many pizzas must the pizzeria sell for employees to receive the bonus? Explain your reasoning. Show your work!
⦁ Suppose the actual number of pizzas sold today was 66. Describe the number of pizzas sold as a percent increase or decrease.
Answer:
a. 90 pizzas
b. 12% decrease
Step-by-step explanation:
To receive a bonus, there must be 20% increase in the number of pizzas
Thus;
20% of 75 = 20/100 * 75 = 1500/100 = 15
So the number of pizza to be sold to receive the bonus will be 15 + 75 = 90
So now, we have 66 pizza sold today;
We can see that there was a decrease from 75
Percentage decrease will be;
(new value - old value)old value * 100%
= (66-75)/75 * 100%
= -9/75 * 100%
= -0.12 * 100% = -12%
This shows a 12% decrease
Anyone know how to solve this !!
Answer:
It's 60
Step-by-step explanation:
All triangles angles have to add up to 180 degrees. 60 plus 60 plus 60 is `80.
Answer:
C. 120°
Step-by-step explanation:
Just by looking at it, you can see that it is over 90° which automatically makes it not 60° and your only option left is 120°

Step-by-step explanation:
Help me?! Solve for x
Answer:
x = 12
Step-by-step explanation:
The consecutive angles in a parallelogram are supplementary, thus
7x - 12 + 108 = 180, that is
7x + 96 = 180 ( subtract 96 from both sides )
7x = 84 ( divide both sides by 7 )
x = 12

Chris found a jacket regularly priced at $90, on sale for 20% off. If there is an 8% sales tax, how much did Chris pay?
(GIVING BRAINLY)
Answer:
$77.76
Step-by-step explanation:
90 x .2 = 18 (20% off)
90 - 18 = 72 (sale price)
72 x .08 = 5.76 (tax price)
72 + 5.76 = 77.76 (total)
When Judy worked 4 hours and Ben worked 1 hour, their combined pay was $75. When Judy worked 2 hours and Ben worked 6 hours, their combined pay was $120. Find the hourly rate of pay for Ben and Judy.
Answer:
$15
Step-by-step explanation:
let the hourly rate of pay for Ben = B
let the hourly rate of pay for Judy = J
Judy worked 4 hours and Ben worked 1 hour, their combined pay was $75;
4J + B = 75 ----- i
Judy worked 2 hours and Ben worked 6 hours, their combined pay was $120
2J + 6B = 120 --- ii
Now, we should solve the expression;
Multiply equation ii by 2 and equation i by 1;
4J + B = 75 ----- i x 1 ; 4J + B = 75 -- iii
2J + 6B = 120 --- ii x 2 ; 4J + 12B = 240 ---iv
Now,
equation iv - iii;
11B = 165
B = $15
So, solving for J;
4J + B = 75
4J + 15 = 75
4J = 75 - 15 = 60
J = $15
In the diagram of AADC below, EB|| DC, ED=60, AB=12, and BC=72. What is the
length of AD?
A
12
E
B
60
72
D
С
Answer:
The length of AD is 70
Step-by-step explanation:
From the given figure
→ In triangle ADC
∵ EB // to DC
→ That means EB divides the sides AD and AC into parts proportional
∴ E divides AD into AE and ED
∴ B divides AC into AB and BC
∴ [tex]\frac{AE}{ED}[/tex] = [tex]\frac{AB}{BC}[/tex]
∵ ED = 60
∵ AB = 12
∵ BC = 72
→ Substitute them in the ratio above
∴ [tex]\frac{AE}{60}[/tex] = [tex]\frac{12}{72}[/tex]
→ By using cross multiplication
∵ AE × 72 = 12 × 60
∴ 72 AE = 720
→ Divide both sides by 72
∴ AE = 10
∵ AD = AE + ED
∴ AD = 10 + 60
∴ AD = 70
∴ The length of AD is 70
Adrian is a songwriter who collects royalties on his songs whenever they are played in a commercial or movie. Adrian will earn $40 every time one of his songs is played in a commercial and $130 every time one of his songs is played in a movie. Adrian earned a total of $1010 in royalties on 14 commercials commercials and movies. Write a system of equations that could be used to determine the number of commercials and the number of movies on which Adrian's songs were played. Define the variables that you used to write the system.
Answer:
commercial = 9
movie = 5
Step-by-step explanation:
Step one:
let the number of commercials be x and movies be y
so
40x+130y=1010-------------1
since there are a total of 14 commercials and movies combined
x+y=14--------------2
Hence the systems of equation is
40x+130y=1010------1
x+y=14-------------------2
Step two:
from equation 2
x=14-y
substui]te the value of x in equation 1
40(14-y)+130y=1010
560-40y+130y=1010
collect like terms
130y-40y=1010-560
90y=450
divide both sides by 90
y=450/90
y=5
movies is 90
put y=5 in equation 2
x+5=14
x=14-5
x= 9
commercial is 9 in numbers
and movie is 5
Answer:
40c+130m=1010
c+m=14
Step-by-step explanation:
Let c=the number of commercials
Let m=the number of movies
system of equations:
40c+130m=1010
c+m=14
Julio has 200 ft of fencing to put around a field that has an area of 2500 sq ft. Write an equation that can be used to find the length of
the field?
Answer:
L = 2500/W
Step-by-step explanation:
Let the fields m be rectangular in nature
Area = LW
Perimeter = 2(L+W)
L is the length
W is the width
Given
Perimeter = 200ft
Area = 2500ft²
Substitute into the formula
200 = 2L+2W
100 = L+W ...... 1
2500 = LW.... 2
From 1; L = 100-W
Substitute into 2
2500 = (100-W)W
100W - W² = 2500
W²-100W+2500 = 0
W²-50W-50W+2500 = 0
W(W-50)-50(W-50) = 0
W - 50 = 0
W =50
Substitute w = 50 into LW = 2500
L = 2500/50
L = 50
Hence the equation that can be used to find the length of the field is
L = 2500/W
