5=z/4−3 This is algebra 1
Answer:
z = 32
Step-by-step explanation:
Add 3 to both sides.
5 + 3 = z/4 -3 + 3
8 = z/4
Multiply 4 on both sides. 8 times 4 is 32.
32 = z

Answer:
Step-by-step explanation:
12x + 2y = 26x - 70
2y = 14x - 70
y = 7x - 35
the answer is A
Answer:
a
Step-by-step explanation:
Given
12x + 2y = 26x - 70 ( subtract 12x from both sides )
2y = 14x - 70 ( divide all terms on both sides by 2 )
y = 7x - 35 → a

2/3c=18 what does c equal to
Answer: 27
Step-by-step explanation:
Answer:
c = 27
Step-by-step explanation:
Solve for c:
(2 c)/3 = 18
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides of (2 c)/3 = 18 by 3/2:
(3×2 c)/(2×3) = 3/2×18
Hint: | Express 3/2×2/3 as a single fraction.
3/2×2/3 = (3×2)/(2×3):
(3×2)/(2×3) c = 3/2×18
Hint: | Express 3/2×18 as a single fraction.
3/2×18 = (3×18)/2:
(3×2 c)/(2×3) = (3×18)/2
Hint: | Cancel common terms in the numerator and denominator of (3×2 c)/(2×3).
(3×2 c)/(2×3) = (2×3)/(2×3)×c = c:
c = (3×18)/2
Hint: | In (3×18)/2, divide 18 in the numerator by 2 in the denominator.
18/2 = (2×9)/2 = 9:
c = 3×9
Hint: | Multiply 3 and 9 together.
3×9 = 27:
Answer: c = 27

Kimberly went to a new animated monster movie yesterday afternoon. When she went into
the movie theater, the outside temperature was -8°F. By the time she left the theater, the
temperature had decreased by 6°F.
What was the temperature when Kimberly left the theater?
Explanation:
Draw a vertical number line. At the center is 0. Anything above this marker represents positive temperatures. Anything below 0 is negative. So we'll have -8 below 0. Move 6 spaces down to go from -8 to -14. You can think of it as moving 6 floors down a building to go from basement level 8 to basement level 14.

The height of a triangle is 4 inches. Greater than twice it's base. The area of the triangle is no more than 168 in.². Which any quality can be used to find the possible lengths, x, of the base of the triangle
Step-by-step explanation:
this problem seeks to test our knowledge on word problems and algebra
Solution
let the base be x, and
the height h = 2x+4
We know that area of a triangle is given as
[tex]A= \frac{1}{2} b*h[/tex]
substituting our given values we have
[tex]168= \frac{1}{2} x*(2x+4)\\\\168= \frac{2x^2+4x}{2} \\\\168= x^2+2x\\\\[/tex]
re-arranging we have
[tex]x^2+2x-168=0\\\\[/tex]
we can now find two factors that will add up to give 2 and multiply to give -168
they are 14 and -12
[tex]x^2-14x+12x-168=0\\\\x(x-14)+12(x- 14)=0\\\\x+12=0\\\\x=-12\\\\x-14=0\\\\x=14[/tex]
The possible base of the triangle is 14 in
and the height is
[tex]h= 2x+4\\\\h=2(14)+4\\\\h= 28+4\\\\\h= 32 in[/tex]

Teresa invested 3000$ in a fund for 5 years and was paid simple interest. The total interest that she received on the investment was 1350$. As a percentage, what was the annual interest rate of her investment?
Answer:
9%
Step-by-step explanation:
To find the answer, you have to use the formula to calculate the interest rate:
r=(1/t)(A/P-1), where
r=rate of interest
A=accrued amount=3000+1350=4350
P=principal amount=3000
t=time periods=5
Now, you can replace the values:
r=(1/5)*(4350/3000-1)
r=0.2*(1.45-1)
r=0.2*(0.45)
r=0.09
According to this, the annual interest rate of her investment is 9%.
You have $250 comma 000 in an IRA (Individual Retirement Account) at the time you retire. You have the option of investing this money in two funds: Fund A pays 2.4% annually and Fund B pays 7.4% annually. How should you divide your money between Fund A and Fund B to produce an annual interest income of $9 comma 000?
Answer:
$190,000 goes to fund A while $60,000 goes to fund B to earn an annual interest income of $9,000
Step-by-step explanation:
Here, we are interested in knowing the way the money should be divided between the interest rates to give an annual interest totaling $9,000.
Let’s have the amount going to Fund A as $x while $y is the amount going to Fund B.
Although, we do not know the value of these amounts, we know that they both total $250,000
Thus, mathematically;
x + y = 250,000 •••••••••••(i)
Now also, let’s work with the percentages to get the interests:
For fund A;
2.4% of x = interest
2.4/100 * x = 2.4x/100
For fund B;
7.4% * y = interest
7.4/100 * y = interest
7.4y/100 = interest
Adding both gives a total of $9,000
Mathematically, that would be;
2.4x/100 + 7.4y/100 = 9,000
Multiply through by 100;
2.4x + 7.4y = 900,000 •••••••(ii)
From i, x = 250,000 -y
Substitute this into ii
2.4(250,000-y) + 7.4y = 900,000
600,000 -2.4y + 7.4y = 900,000
Collecting like terms, we have;
7.4y-2.4y = 900,000-600,000
5y = 300,000
y = 300,000/5
y = $60,000
But x = 250,000 - y
x = 250,000 - 60,000
x = $190,000

A square image of an object on a video game has an initial side length of 25 pixels. To make the object appear closer, the side length of the square is increased by 10 pixels per second. This length change is represented by the function s(t) = 25 + 10t, where t is time in seconds. If the area of the square is A(s) = sa, find the formula for the area as a function of time, and then determine A(s(3)). A(t) equals +2+ t + 625 The area of the square image after 3 seconds is square pixels.
Answer: A(t) = 100t^2 + 500t + 625
3,025 square pixels
Step-by-step explanation:
A function assigns the values. The area of the square image after 3 seconds is 3,025 sq. pixels.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
A.) The area of the video game will be,
A(s) = [s(t)]²
A(s) = (25+10t)²
A(s) = 625 + 100t² + 500t
A(s) = 100t² + 500t +625
B.) The value of A(s(3)) will be,
A(s(t)) = 100(25+10t)² + 500(25+10t) + 625
A(s(t)) = 10,000t² + 50,000t + 62,500 + 12,500 + 5,000t + 625
A(s(t)) = 10,000t² + 55,000t + 75,625
A(s(3)) = 10,000(3)² + 55,000(3) + 75,625
A(s(3)) = 270,000 + 165,000 + 75,625
A(s(3)) = 510,625
The area of the square image after 3 seconds is,
A(s) = 100t² + 500t +625
A(3) = 100(3)² + 500(3) +625
A(3) = 900 + 1500 +625
A(3) = 3,025
Hence, The area of the square image after 3 seconds is 3,025 sq. pixels.

What fractions are equal to 2/3
Answer:
Step-by-step explanation: yes
Answer: 4/6, 6/9, 8/12, 10/15 are all fractions equal to 2/3.
Step-by-step explanation: If you multiply both numerator and denominator in the fraction by any number, the new multiplied fraction will still be equal to the original fraction because fractions are proportionate.
For example: you can multiply 2/3 by 3.
2 x 3 = 6
3 x 3 = 9
6/9 is equal to 2/3 because the proportions are the same.
Another example: you can multiply 2/3 by 4.
2 x 4 = 8
3 x 4 = 12
8/12 is equal to 2/3 because, like before, the proportions are the same.
