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.

General Formulas and Concepts:
Order of Operations: BPEMDASComplementary Angles: Angles that add up to 90°Step-by-step explanation:
Step 1: Set up equation
(8y - 2)° + 60° = 90°
Step 2: Solve for y
Combine like terms: 8y + 58 = 90Subtract 58 on both sides: 8y = 32Divide both sides by 8: y = 4Solve the equation

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.

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
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

Marc plans to create a model of the solar system for his school’s science fair. He knows the solar system includes many celestial bodies.
Which statement identifies a possible limitation of this model?
A. The model will be supported with scientific evidence.
B. The model will include all planets of the solar system.
C. The model will be used to predict planet distances and sizes.
D. The model will oversimplify what the solar system looks like.
Answer:
C) The model will be used to predict planet distances and sizes.
Step-by-step explanation:
A model is used to distort the size and shape of the observed object. Therefore, a model of the solar system will not be accurate when it comes to the planet's distances and sizes. It would take miles upon miles to accurately show the distance between planets.
