i was absent the day they taught this and my teacher refuses to teach me
Step-by-step explanation:
it's something in algebra i don't remember but basically the top number (12) has the x on the bottom which is multiplication and the bottom number (8) has addition so those tell u how ur supposed to get those numbers
so basically u need to find two numbers that add up to 8 and multiply to 12 so the factors are 6 and 2 because 6 • 2 is 12 and 6 + 2 = 8. hope this helps
Answer:
6 and 2
Step-by-step explanation:
6 x 2= 12
6 + 2= 8

solve for y
6x - 3y = 15
hint - subtract 6x, divide by -3, simplify
Answer:
y=2x-5
Step-by-step explanation:
1) Factor out the common term 3
3(2x-y)=15
2)Divide both sides by 3
2x-y=15/3
3) Simplify 15/3 to 5
2x-y=5
4) Subtract 2x from both sides
-y=5-2x
5) Multiply both sides by -1
y=-5+2x
6) regroup terms
y=2x-5
can someone please help
Answer:
3rd option
Step-by-step explanation:
Substitute x = 0 into f(x) and check if the result is - 6
f(0) = (0 + 1)(0 + 2)(0 + 3) = 1 × 2 × 3 = 6 ≠ - 6
f(0) = (0 + 1)(0 - 2)(0 - 3) = 1 × - 2 × - 3 = 1 × 6 = 6 ≠ - 6
f(0) = (0 - 1)(0 + 2)(0 + 3) = - 1 × 2 × 3 = - 1 × 6 = - 6 ✔
Thus the 3rd option crosses the y- axis at (0, - 6 )

What value of x would result in the numerical value of zero in the expression?
x+1+(−1)
Answer:
x = 0
Step-by-step explanation:

50°
A) 65°
C) 50°
B) 45°
D) 46°
Answer:
B
Step-by-step explanation:
i estimated this answer
Answer:
= 50, C
Step-by-step explanation:
? = 50
This is because the 50 shown is vertically opposite to the unknown angle, which they are equal
(Vertically opposite angles can be formed between two opposing lines)

Answer: Check out the diagram below.
Explanation:
Use a calculator to find that:
[tex]A = \sqrt{18} \approx 4.24\\\\B = \sqrt{73} \approx 8.54\\\\C = \sqrt{30} \approx 5.48\\\\D = \sqrt{52} \approx 7.21\\\\E = \sqrt{7} \approx 2.65\\\\[/tex]
You'll then plot those decimal approximate values on the number lines given.
For example, 4.24 will go somewhere between 4 and 5. It's closer to 4 than it is to 5. The other values are handled the same way. The placement of the points doesn't have to be perfect.
Check out the diagram below. I made one single number line and plotted all the values on it. However, you'll have 5 separate number lines (one value per number line).
How do I calculate a angle that is not named?

A diver descended 43.52 feet in 13.6 minutes. What was the diver's average change in elevation per
minute?
1/11 as a decimal
59/9 as a reduced mixed number
Answer:
1. .09 repeating 2. 6 5/9
Step-by-step explanation:
to turn a fraction into a decimal you divide the top number of a fraction by the bottom one. To convert an improper fraction to a mixed fraction, divide the numerator by the denominator, write down the quotient as the whole number and the remainder as the numerator on top of the same denominator
Mrs. Glaser was extremly hungry one day and decided to eat some delicious tacos. She bought 6 tacos for 10$ and this rate houch would 4 tacos cost?
Answer: First you want to divide $10 from 6 tacos. You should get a number like 1.6666 continuing, the. You want to multiply the 4 tacos times the answer you got from 10/6 so your problem would look like 1.66667 x 4
You should get 6.6667 or you can sum it up with 6.67 or $6.70
Each face of a pyramid is an isosceles triangle with a 72 degree vertex angle. What are the measures of the base angles?
Answer:
52° and 52°
Step-by-step explanation:
An isosceles triangle has two base angles that are congruent. So let x be the measure of the base angle so that by Triangle Angle-Sum Theorem, we can write: X+X+76=180 and next would be 2X+76=180 and then it would be 2X=104 and finally it would be X=52. So there for the measures of the base angles are 52° and 52°. There hoped it helped!!!!

Answer:
x=12
10x = 120
5x = 60
Step-by-step explanation:
paralellograms will become 360 degrees
so 2(5x) +2(10x)= 360
Simplify:
10x + 20x = 360
= 30x
divide both sides by 30 and isolate
30x = 360
30 30
x=12
multiply 12 by 10x and 5x
10x = 120
5x = 60
determine the intercepts of the line

2. what equation passes through the 2 points (0,5) and (-12, -1)
You are remodeling your kitchen. You have contacted 2 tiling companies who gladly told you how long it took their workers to tile a floor of a similar size. Jim completed 1/2 the floor in 12 hours, Pete completed the other 1/2 in 10 hours. If Pete can lay 25 more tiles per hour than Jim, what equation would you use to find the rate that Jim can lay tiles? Let x represent Jim's rate.
A. 10x = 12 (x -25)
B. 12x = 10 (x + 25)
C. 10x = 12 (x + 25)
D. 12x = 10 (x - 25)
Hence, Jim can lay 125 tiles and Pete can lay 25 more so 125+25=150 tiles.
