Step-by-step explanation:
Simplifying
3(2x + -1) = 21
Reorder the terms:
3(-1 + 2x) = 21
(-1 * 3 + 2x * 3) = 21
(-3 + 6x) = 21
Solving
-3 + 6x = 21
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + 6x = 21 + 3
Combine like terms: -3 + 3 = 0
0 + 6x = 21 + 3
6x = 21 + 3
Combine like terms: 21 + 3 = 24
6x = 24
Divide each side by '6'.
x = 4
Simplifying
x = 4
Answer:
2/3x + 7s
Step-by-step explanation:
-1/3 ( -2x - 21) = -1/3 * (-2x) - (-1/3) * 21 = 2/3x - (-7) = 2/3x + 7s

Suppose your school costs for this term were $4780 and financial aid covered 3/4 of that amount. How much did financial aid cover? How much do you still have to pay?
Answer: Amount covered by financial aid=$3,585
Amount left that you have to pay =$1,195
Step-by-step explanation:
School cost for the term = $4780
Amount covered by financial aid = 3/4 of $4780
= 3/4 x 4780
Amount left that you have to pay=School cost for the term -Amount covered by financial aid
= $4,780 - $3,585
Amount left that you have to pay =$1,195
is 3 1/2 greater than 1 1/15
Answer:
Yes
Step-by-step explanation:
The whole number in 3 1/2 is 3
the whole number in 1 1/15 is 1
Since 1 1/15 isn't an improper fraction, if it's whole number is smaller then the whole fraction is smaller
since 3>1, 3 1/2 is greater than 1 1/15
Answer:
31/2 > 11/15
Step-by-step explanation:
Question: Is 31/2 greater than 11/15 ?
To solve this let us convert the fractions to decimals.
31/2 = 15.5
11/15 = 0.733
With a look we can easily say that 31/2 is indeed greater than 11/15.
So, 31/2 > 11/15.

Tina has an old fish tank in the shape of a circular cylinder. The tank is 2 feet in diameter and 6 feet high. How many cubic feet of water does it hold?
Answer:
The tank can hold 18.84 cubic feet
Step-by-step explanation:
Given
Shape: Cylinder
[tex]D = 2ft[/tex] -- Diameter
[tex]H = 6ft[/tex] -- Height
Required
Determine the volume
First, calculate the radius (r)
[tex]r = \frac{1}{2}D[/tex]
[tex]r = \frac{1}{2}*2ft[/tex]
[tex]r = 1ft[/tex]
The volume (V) of the tank is:
[tex]V = \pi r^2h[/tex]
Substitute values for r and h
[tex]V = 3.14 *1^2*6[/tex]
[tex]V = 3.14 *1*6[/tex]
[tex]V = 18.84[/tex]
Hence, the tank can hold 18.84 cubic feet

What is the equation of a line perpendicular to the x-
axis that passes through the point (-5,-1)? What is the
slope of this line?
Answer:
The equation is x = -5
The slope is 0
Step-by-step explanation:
If the line is perpendicular to the x axis, that means it is a vertical line.
Vertical lines only reach one x value, which is -5 in this case.
So, the equation will simply be x = -5.
The slope is 0.

Eyan bought 234 pounds of apples for $1.32 per pound, 112 pounds of peaches for $1.20 per pound, and some tomatoes, all from a grocery store. The total cost of his purchase was $9.63. How much money did Leyan spend on tomatoes?
Answer:
the money spend on tomatoes is $4.20
Step-by-step explanation:
The computation of the money spend on tomatoes is shown below
Let the money spend on tomatoes be x
So
[tex]2 \frac{3}{4} \times \$1.32 + 1\frac{1}{2} \times \$1.20 + x = \$9.63\\\\[/tex]
$3.63 + $1.80 + x = $9.63
x = $9.63 - $3.63 + $1.80
= $4.20
Hence, the money spend on tomatoes is $4.20

Rita is designing a building shaped like a pyramid that's cut off in a plane parallel to its base (this is called a truncated pyramid).The building has a 64 × 64 m square base and is 36 m tall. The cut off section has a 16 × 16 m, square base and is 12 m tall. What is the volume of the buliding?
Answer:
65,536−1,024
which = 64,512 m^3
Step-by-step explanation:
I took the test!
The volume of the building shaped like a pyramid that's cut off in a plane parallel to its base is 64512 m³
Volume of a pyramidvolume of a pyramid = 1 / 3 Bh
where
B = base areah = height of the pyramidTherefore,
volume of the building = volume of the whole figure - volume of the cut part
volume of the whole figure = 1 / 3 × (64 × 64) × (12 + 36)
volume of the whole figure = 65536 m³
volume of the cut part = 1 / 3 × (16 × 16) × (12)
volume of the cut part = 1024 m³
Therefore,
volume of the building = 65536 - 1024 = 64512 m³

Which of the following expressions represents a value greater than 4/5 ?
Answer:
For the two fractions 4/5 and 5/6, the least common denominator is 30. The fraction 4/5 is equivalent to 24/30 (To get this I multiplied both the numerator and denominator by 6). ... Since 25 is greater than 24, 25/30 (or originally 5/6) is the larger fraction
Step-by-step explantion
Compare fractions with the same denominator by determining the relationship between the numerators. For example, 3/5 is less than 4/5 because 3 is less than 4
A shipping container will be used to transport several 70-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 23500 kilograms. Other shipments weighing 9700 kilograms have already been loaded into the container. What is the greatest number of 70-kilogram crates that can be loaded into the shipping container?
Subtract what has already been loaded from total amount allowed:
23500 - 9700 = 13,800
Divide the amount left by the weight of each crate:
13,800 / 70 = 197.14
They can load 197 crates.

Find the remainder when x^100 - x^99 + x^98 − · · · − x + 1 is divided by x + 1.
Answer:
The remainder is 101.
Step-by-step explanation:
We are dividing:
[tex](x^{100}-x^{99}+x^{98}...-x+1)\div(x+1)[/tex]
By the Polynomial Remainder Theorem, if we are dividing a polynomial P(x) by a binomial in the form (x - a), the our remainder will be P(a).
The divisor is (x + 1). Therefore, our a = -1.
Then the remainder will be:
[tex]P(-1)[/tex]
We can rewrite our polynomial as:
[tex]P(x)=-(x^{99}+x^{97}...+x^3+x)+(x^{100}+x^{98}...+x^2)+1[/tex]
Each of the parentheses contain fifty terms. -1 to any odd power is -1, and -1 to any even power is 1. Therefore:
[tex]P(-1)=-(-50)+(50)+1[/tex]
Evaluate:
[tex]P(-1)=101[/tex]
The remainder is 101.
