Noelle and Gina have a combined height of 130 inches. Noelle is 4 inches taller than Gina. Let n stand for Noelle's height. How tall is each girl?
Gina's height in inches:______________________
Noelle's height in inches:_______________________
Equation:____________________________
Answer:
Gina's height in inches: 63 inches
Noelle's height in inches: 67 inches
Equation: n + (n - 4) = 130
Step-by-step explanation:
n + (n - 4) = 130
n + n - 4 = 130
2n - 4 = 130
2n - 4 + 4 = 130 + 4
2n = 134
2n ÷ 2 = 134 ÷ 2
n = 67
67 - 4 = 63

CDEF is a parallelogram. Solve for x.
Answer:
x = 12
Step-by-step explanation:
24 = 3x - 12 (opposite sides of a parallelogram are equal)
24 + 12 = 3x
36 = 3x
36/3 = x
12 = x
Answer:
x=13
Step-by-step explanation:
The parallel sides on a parallelogram are equal, therefore you must find a number that would satisfy the requirement for equality in the sides' length
So lets get started by finding out what number would be 24 after 12 has been subtracted from it.
24+12=36
Now we need to find out how to get 36 from 3x
36/3=13
13.
x is 13.
Now lets check that our answer is right
13x3=36
so far so good.
36-12=24
That checks out.
24=24.

A correct answer without a CHECK and work/ explanation will NOT receive full credit! NOTE: Press and hold the SHIFT button and press 6 to make the "^" exponent symbol. Someone plz help its doe in 10 min
Answer:
The factors of x² - 3·x - 18, are;
(x - 6), (x + 3)
Step-by-step explanation:
The given quadratic expression is presented as follows;
x² - 3·x - 18
To factorize the given expression, we look for two numbers, which are the constant terms in the factors, such that the sum of the numbers is -3, while the product of the numbers is -18
By examination, we have the numbers -6, and 3, which gives;
-6 + 3 = -3
-6 × 3 = -18
Therefore, we can write;
x² - 3·x - 18 = (x - 6) × (x + 3)
Which gives;
(x - 6) × (x + 3) = x² + 3·x - 6·x - 18 = x² - 3·x - 18
Therefore, the factors of the expression, x² - 3·x - 18, are (x - 6) and (x + 3)

The scale on the map indicates 1 inch= 150 miles. The distance from Philadelphia to Miami is 1200 miles. on the map, how far apart are Philadelphia and Miami?
9514 1404 393
Answer:
8 in
Step-by-step explanation:
(1200 mi)×(1 in)/(150 mi) = (1200/150) in = 8 in
The cities are 8 inches apart on the map.
_____
Additional comments
You can think of it as a units conversion problem (as above), or as a proportion:
(map distance)/(1200 mi) = (1 in)/(150 mi)
map distance = (1200 mi)(1 in)/(150 mi) = 1200/150 in = 8 in
__
When doing units conversion, you multiply by a scale factor that has units you want in the numerator, and units you want to cancel in the denominator. The numerator and the denominator have the same value, so multiplying by that fraction changes the units but not the value. Here, 1 in = 150 mi, so (1 in)/(150 mi) ≡ 1.

1. Shaded area is 14 cm. Find r to the nearest 0.01 cm.
Answer:
Step-by-step explanation:
Area of the quarter circle = 1/4 pi * r^2
Area of the quarter circle = 1/4 * 3.14 * r^2
Area of the triangle = 1/2 r * r = 1/2 r^2
Equation of Solution
1/4 3.14 * r^2 = 14 cm^2 + 1/2 * r^2 Subtract 1/2 r^2 from both sides
0.785 r^2 - 0.5 r^2 = 14 cm^2 Combine the left
0.285 r^2 = 14. cm^2 Divide by 0.285
r^2 = 14/0.285
r^2 = 49.1228 Take the square root of both sides
sqrt(r^2) = sqrt(49.1228)
r = 7.01

Pearl bought 45 lbs of clay for her art projects. She used 15.8 lbs to make a sculpture, and 0.72 lbs for each mug. How many mugs did Pearl make if she had 17.68 lbs of clay left over?
Answer:
16 mugs
Step-by-step explanation:
Total clay bought = 45 lbs
Clay used for sculpture = 15.8 lbs
Clay left over = 17.68 lbs
Clay used for each mug = 0.72 lbs
Number of mug = x
Total clay bought = Clay used for sculpture + Clay left over + (Clay used for each mug * Number of mug)
45 = 15.8 + 17.68 + (0.72 * x)
45 = 33.48 + 0.72x
45 - 33.48 = 0.72x
11.52 = 0.72x
x = 11.52/0.72
x = 16
Number of mug = x = 16 mugs

what are all of the steps to get 7(3x-1)-(x+5)
Answer:
20x-12
Step-by-step explanation:
Given:
7(3x−1)−(x+5)
Step 1: Distribute the Negative Sign:
=7(3x−1)+−1(x+5)
=7(3x−1)+−1x+(−1)(5)
=7(3x−1)+−x+−5
Step 2: Distribute:
=(7)(3x)+(7)(−1)+−x+−5
=21x+−7+−x+−5
Step 3: Combine
=21x+−7+−x+−5
=(21x+−x)+(−7+−5)
=20x+−12
Answer:

Step-by-step explanation:
Remember, P.E.M.D.A.S. Parenthesis first so 3x-1 and x+5. Not given enough information, I cannot give you the correct answer so instead, I will give you the equations you will have to do and these are not all in the order of what you have to do, but most of them are. Just follow P.E.M.D.A.S. if you know what to do. (I will put letters as answers)
step 1: (3x-1)
3 times x = Q
Q minus 1 = P
step 2: (x+5)
x plus 5 = E
step 3: 7xP
7 times P = W(The one from step 1)
step 4: W-E
W-E= A

Explanation:
Question: "What is the GCF of 30, 42, and 12?
You may ask, "How did you get the answer?"
1) Let's list out the factors of 30, 42, and 12.
30 - 1, 2, 3, 5, 6, 10, 15, 30
42 - 1, 2, 3, 6, 7, 14, 21, 42
12 - 1, 2, 3, 4, 6, 12
What are the common numbers from the list?
1, 2, 3, 6
What is the greatest number from the list of the common numbers?
6
Now let's separate the variables and find the common factor of the variables.
Variables:
w 2 , w 4 , w * w
can also be thought of as w 1 .
Since
w
is the lowest powered variable and all of the other ones are greater than that. Then it means that the common factor of the variables is
w .

Since w is the lowest powered variable and all of the other ones are greater than that. Then it means that the common factor of the variables is
w.
Let's combine what we've found out now!
The GCF of the integers is 6 and the common factor of the variables is
w
. Therefore, the GCF is 6w!
