Expand 4(-2y + 3).
-8y + 12
2y + 7
-8y + 3
2y + 12
Answer:
-8y+12
Step-by-step explanation:
4(-2y +3)
you can distribute the 4
4 • -2y + 4 • 3
= -8y +12
because they are not like terms, you cannot do anything further.

suppose 4<a<7. find all the possible values of 15-2a
9514 1404 393
Answer:
1 < 15 -2a < 7
Step-by-step explanation:
There are a couple of ways you can do this.
1) Put the minimum and maximum values of a into the expression to see what its corresponding values are:
15-2a for a=4:
15-2(4) = 7
15-2a for a=7:
15-2(7) = 1
Then ...
1 < 15-2a < 7
__
2) Solve for a in terms of the value of 15-2a, then impose the limits on a.
x = 15 -2a
2a = 15 -x
a = (15 -x)/2
Now, impose the given limits:
4 < (15 -x)/2 < 7
8 < 15 -x < 14 . . . multiply by 2
-7 < -x < -1 . . . . . . subtract 15
7 > x > 1 . . . . . . . . multiply by -1
1 < 15-2a < 7 . . . . . use x=15-2a
_____
The vertical extent of the attached graph is the range of possible values of 15-2a. It goes from 1 to 7.

I have 5 digits. My q is worth q * 10,000. My 2 is worth 2 thousand. One of my 7s is worth 70. The other is worth 10 times as much. My other digit is a 6. What number am l
Answer:
92,776
Step-by-step explanation:
I have 5 digits. My 9 is worth 9*10,000. My 2 is worth 2 thousand. One of my 7s is worth 70. The other is worth 10 times as much. My other digit is a 6. What number am I?
My 9 is worth 9*10,000 = 9 * 10,000
= 90,000
My 2 is worth 2 thousand = 2,000
One of my 7s is worth 70 = 70
The other is worth 10 times as much = 70 * 10
= 700
My other digit is a 6 = 6
The number is
90,000 + 2,000 + 700 + 70 + 6
= 92,776

1. In the office, there is a filing cabinet that is 1 foot wide, 3 feet deep and 3
feet tall. You have hundreds of file folders to put into this cabinet.
Assuming that each folder is 12 inches wide, 1 inch thick, and 9 inches
tall, how many folders can you fit into this cabinet? (Draw a picture!)
Answer:
the answer is 144 folders
Step-by-step explanation:
you have to convert the ft of the file cabinet to inches. so the cabinet is 12 in wide, 36 in deep and 36 in tall. the volume of it is 15,552 cu in. each folder is 108 cu in. divide 15,552 by 108 = 144 folders can fit in the cabinet. sorry my pic is messy.

Answer:
Δ QRS is an obtuse triangle ⇒ according to its angle
Δ QRS is an isosceles triangle ⇒ according to its sides
Step-by-step explanation:
In Δ QRS
∵ m∠Q = 8x - 17
∵ m∠R = 19x + 4
∵ m∠S = 5x + 1
→ The sum of the interior angles of a Δ is 180°
∴ m∠Q + m∠R + m∠S = 180°
→ Substitute their values in the equation above
∵ 8x - 17 + 19x + 4 + 5x + 1 = 180
→ Add the like terms
∴ (8x + 19x + 5x) + (-17 + 4 + 1) = 180
∴ 32x + (-12) = 180
∴ 32x - 12 = 180
→ Add 12 to both sides
∵ 32x - 12 + 12 = 180 + 12
∴ 32x = 192
→ Divide both sides by 32
∵ [tex]\frac{32x}{32}[/tex] = [tex]\frac{192}{32}[/tex]
∴ x = 6
→ Substitute the value of x in each measure of angles to find them
∵ m∠Q = 8(6) - 17 = 48 - 17
∴ m∠Q = 31°
∵ m∠R = 19(6) + 4 = 114 + 4
∴ m∠R = 118°
∵ m∠S = 5(6) + 1 = 30 + 1
∴ m∠S = 31°
∵ m∠R > 90°
∴ ∠R is an obtuse angle
∴ Δ QRS is an obtuse triangle
∵ m∠Q = m∠S
→ In any Δ if two angles are equal in measures, then the two sides
opposite to these angles are equal in length and the Δ is isosceles
∴ RQ = RS
∴ Δ QRS is an isosceles triangle
(9,-8) and (9,6) and determine the equation of the line.
Answer:
The answer is undefined.
Step-by-step explanation:
The x will never change, no matter what the y is, so the answer will always be undefined.
20% tip on a $30 hair cut
Answer:
Step-by-step explanation:
Turn
Just turn the percentage into a decimal, in this case turn 20% into the decimal form .20.
Multiply
Multiply the decimal by the dollar.
.20 x 30 = 6$.
This applies to other questions similar to this. Turn the percentage into a decimal.
102% of 50$
102% = 1.02
1.02 x 50 = 51 $
3% of 8$
3% = 0.03
0.03 x 8 = 0.24 $
Can two people with blue eyes have a child with brown eyes? Why or why not? also i really don´t really know the subject so i put it in math.
Answer:
Yes
Step-by-step explanation:
In the family the blue eyed people may have had a gene with brown eyes. So if both parents carry that gene even if they don't display it, it can be still shown because brown eyes are the most dominant trait.
BR Elder 1: BL BR BL Elder 2: BL BL BL Elder 1: BL BL BL Elder 2: BR BL
I I I I
I I
Parent 1: Blue gene brown gene Parent 2: Blue gene brown gene
I I
I
Child Brown eyes: BR BL
Because the brown gene is dominant if the gene shows up in both parents the child would be more likely to have brown eyes than blue.

How can we get Equation B from Equation A?
3(x+2)=18
x+2=18
i need them solved aswell
Answer:
x = 4
Step-by-step explanation:
A:3(x+2)=18
Divide each side by 3
3/3(x+2)=18/3
x+2 = 6
This is the same equation as equation B
They will have the same solution since they are the same equation
x+2-2 = 6-2
x = 4

Jordan is mixing water and flour to make tortillas. The
number of cups of water, w, needed for f cups of flour
is described by the equation w= = 0.75f
How many cups of water are needed to mix with 4 cups
of flour?
Please help!!!
Answer:
w = 3 cups when f = 4 cups
Step-by-step explanation:
Given:
w = 0.75f
Where,
w = number of cups of water
f = number of cups of flour
Find w when f = 4 cups
w = 0.75f
Substitute f = 4 into the equation
= 0.75(4)
= 3
w = 3 cups when f = 4 cups
