The equation given was: (x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87.
Using this equation, write the equation with fewer terms.
Answer:
x = 13
Step-by-step explanation:
(x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87
x + x + 3 + x - 2 + 3x + 9 - 1 = 87
6x + 9 = 87
6x = 87 - 9
6x = 78
x = 78/6
x = 13

Find the x−and y−intercepts of −2x − 12y = 24.
Will give Brainliest!
Answer:
X= -12 -6y, Y= -2- x/6
Step-by-step explanation:
For x
-2x-12y=24
-2x/-2 -12y/-2. 24/-2. Divide all by -2
X+6y=-12 this is what you get after
-6y. -6y. Subtract from both sides
X=-12-6y this is what you get
Find y
-2x-12y=24
-2/-2. -12/-2. 24/-2
X -6y=-12
-x. -x
-6y=-12-x
-6y/-6. -12/-6. -x/-6
Y = -2 - x/6

The cost of 4 bananas is $2.36. What is the cost of each banana?
Mario's Work. StartFraction b Over 4 EndFraction = 2.36. A number line going from 9.41 to 9.49. A point is at 9.44.
Juan's Work. 4 b = 2.36. A number line going from 0.51 to 0.59. A point is at 0.59.
Daviana's Work. B minus 4 = 2.36. A number line going from 6.31 to 6.39. A point is at 6.36.
Answer:
B i think
Step-by-step explanation:
Juans work is correct because the equation to find cost of each banana is 4b=$2.36
What is Number system?A number system is defined as a system of writing to express numbers.
Given that the cost of 4 bananas is $2.36
We have to find the cost of each banana.
To find this we have to divide the cost by number of bananas
Divide two point three six by four
Banana is denoted by b
4b=$2.36 is the required equation
Cost of each banana =$2.36/4
=$0.59
Hence, Juans work is correct because the equation to find cost of each banana is 4b=$2.36

2x−5=5x−2
Step 2: Subtract 5x from both sides.
2x−5−5x=5x−2−5x
−3x−5=−2
Step 3: Add 5 to both sides.
−3x−5+5=−2+5
−3x=3
Step 4: Divide both sides by -3.

24 is 40% of what number? Use the percent equation.
Divide 24 by 40%
24 / 0.40 = 60
The answer is 60
Using the percentage equation, 24 ( twenty four ) is 40% ( forty percent ) of 60 ( sixty ).
What is Percentage?Percentage is simply number or ratio expressed as a fraction of 100.
The perecent equation is expressed as;
Percentage = ( Part / Whole ) × 100%
Given the data in the question;
Percentage = 40%Part = 24Whole = ?We determine the number, we substitute our given values into the expression above.
Percentage = ( Part / Whole ) × 100%
40% = ( 24 / Whole ) × 100%
40/100 = ( 24 / Whole ) × 100/100
40/100 = 24 / Whole
We cross multiply
40 × Whole = 24 × 100
40 × Whole = 2400
Whole = 2400 / 40
Whole = 60
Therefore, using the percentage equation, 24 ( twenty four ) is 40% ( forty percent ) of 60 ( sixty ).
