In the two-step equation below, what is the first step you would take to solve this equation?
-7+4r=-15
a. Divide both sides by 4.
b. Add 7 to both sides.
c. Multiply both sides by 4.
Selected:d. Subtract 7 from both sides.
Answer:
b
Step-by-step explanation:
-7 + 4r = -15
+7 +7
4r = -8
divide both sides by 4
r = -2
Hope this Helps!!!
Answer:
b. Add 7 to both sides.r=-2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4r−7=−15
Step 2: Add 7 to both sides.
4r−7+7=−15+7
4r=−8
Step 3: Divide both sides by 4.
4r/4=−8/4
r=−2

=a2+2ax+x2+−b2+2bx+−x2+x2+(a)(x)+(−b)(x)+−a2b2y+−ab3y
=a2+2ax+x2+−b2+2bx+−x2+x2+ax+−bx+−a2b2y+−ab3y
Combine Like Terms:
=a2+2ax+x2+−b2+2bx+−x2+x2+ax+−bx+−a2b2y+−ab3y
=(−a2b2y)+(−ab3y)+(a2)+(2ax+ax)+(−b2)+(2bx+−bx)+(x2+−x2+x2)
=−a2b2y+−ab3y+a2+3ax+−b2+bx+x2

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.
Hakim received some gift cards for music and movie downloads for his birthday. Using one of them, he downloaded 20 songs and 13 movies, which cost a total of $163. Using another, he purchased 13 songs and 13 movies, which cost a total of $156. How much does each download cost?
Downloads cost $____for a song and $______ for a movie.
Answer:
the download cost for a song is $1 and $11 for a movie
Step-by-step explanation:
According to the questions, the following equations are as follows:
Let us assume the song be x
And, the movies be y
So,
20x + 13y = $163.........(i)
13x + 13y = $156........(ii)
Now solve substract second equation from the first equation
7x = $7
x = $1
And the y value is
20 + 13y = $163
13y = $163 - $20
13y = $143
y = $11
Hence, the download cost for a song is $1 and $11 for a movie

Carin has 2/3 of a bottle of paint. She uses 1/6 of a bottle to paint one model airplane. How many model airplanes can carin paint with 2/3 of a bottle of paint. Answer
Answer:
4
Step-by-step explanation:
Given that :
Total fraction of paint Carin has = 2/3 bottle
Fraction used to paint a model airplane = 1/6
Number of model. Airplanes 2/3 of a bottle could paint ;
Total fraction of paint / fraction used to paint a model airplane
(2/3) ÷ (1/6)
2/3 * 6/1
= 12 / 3
= 4 model airplanes
Plug in the point (1,6) into the inequality 4x-3y<12 to determine if the point is in the solution set. How do you know
A Yes, (1,6) is in the solution set because the truth value is TRUE
B No, (1,6) is not the solution because the truth value is FALSE
Answer:
false
Step-by-step explanation:
4(1) - 3(6)<12
4 - 18<12
12<12
so no the truth value is false 12 is not less than 12
Answer:
A. true
Step-by-step explanation:
If you plug in x and y, the equation is 4(1)-3(6)<12. SImplify to get 4-18<12 which is equal to -14<12 which is true.
4.5 is 7.5% of what number?
Answer:
60
Step-by-step explanation:
The required number is 60.
What is percent?In mathematics, a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".
Now the given expression is,
4.5 is 7.5%
Let x be the number.
Therefore, 7.5% of x is 4.5
⇒ 7.5% of x = 4.5
⇒ 7.5% * x = 4.5
⇒ 7.5/100* x = 4.5
⇒0.075 x = 4.5
Dividing both side by 0.075 we get,
x = 4.5 / 0.075
Solving we get,
x = 60
this is the required number.
Thus,the required number is 60.
