I'm using the second question as an example.
To find the Unit Rate, you have to divide the amount of money by the amount of whatever the product is
5.99/8= 0.74875
Since the question says to round it to the nearest hundredth, that means the price per unit (unit rate, or the price for one battery here) would be about $0.75. Simple, right?
Write an equation of the line that passes through each pair of points (- 2, - 3), (4, 5)
Answer:
y= 4/3x -1/3
Step-by-step explanation:
Find slope: y2-y1/x2-x1 = 5-(-3)/4-(-2) = 8/6 = 4/3
Use point slope to find the equation:
y - y1 = m ( x - x1 )
y - (-3) = 4/3 ( x - (-2))
y = 4/3x + 8/3 + (-3)
y = 4/3x + 8/3 - 9/3
y= 4/3x -1/3

4⋅(4d+5)
Step-by-step explanation:
In an election for school president, the loser received 70% of the winner's votes. If 969 votes were cast, how many did each receive?
Answer:
The ans would be 291 (however we can round this off to 290 as no can partially vote as 0.1)
Step-by-step explanation:
We can easily find the loser's vote by-
70% of 969= 678.9
now, all we need to do is find the winners vote
we know that the total no. of votes= 969 & we know the no. of votes loser got
so, subtracting the losers vote from 969 would give us the remaining no. of votes (the winner's votes)....so,
969-678.9=290.1
we can round this off to 290

adding fractions with unlike denominators 1/3 + - 2/7
Answer:
1/21
Step-by-step explanation:
Changing operations to eliminate negative numerators the equation becomes
=1/3−2/7
With unlike denominators find the Least Common Denominator (LCD)
LCD = 21
Multiplying numerators and denominators to get the LCD in all fraction denominators
=1×7/3×7 −2×3 /7×3
Then rewriting the equation with the equivalent fractions
=7/21−6/21
With like denominators we can operate on just the numerators
=7−6/21
=1/21

Answer:
M = 7x² +21
Step-by-step explanation:
Subtract the unwanted terms on the left from both sides.
(-7x² +6x -16) + M = 6x +5
M = 6x +5 -(-7x² +6x -16)
M = 7x² +21 . . . . simplify
When someone donated 14 gallons of paint to Rosendale Elementary School, the fifth grade decided to paint a mural. They split the gallons equally among the four classes.
b. how much paint will three classes use?
c. If 4 students share a 30-square footwall equally, how many square feet of the wall will be painted by each student?
d. what fraction of the wall will each student paint?
Answer:
Step-by-step explanation:
So, first we can do 14/4 which is 3.5
Each class uses 3.5 gallons
For (B), we can do 3.5 * 3 which equals 10.5 gallons
For (C), we can do 30÷4 which is 7.5 square feet
For (D) they each paint 1/4 of the wall

TS is an angle bisector. If m∠RTS=x+10 and m∠UTS=2x+5, find m∠RTU.
answer choices below
30°30 degrees
15°15 degrees
80°80 degrees
5°
Answer:
m∠RTS= 15°, m∠UTS= 15°, m∠RTU= 30°
Step-by-step explanation:
Since TS bisects RTS and UTS, that means the two angles are equal to each other. So let's find x first.
x+10=2x+5, subtract x to both sides
10=x+5, subtract 5 to both sides
x=5
Since RTU is basically RTS plus UTS, let's add the two angles together
x+10+2x+5, combine like terms
3x+15
Then we can plug in 5 for x
3(5)+15
15+15
=30
So, RTU is 30 degrees

6) Choose which postulate proves the triangles congruent.
Answer:
SAS(Side.Angle.Side
Step-by-step explanation:
since x is mid point of pr and qs so px=xr and x is midpoint of qs so qx=sx,
and two lines intercept so angles made on point x are equal.....hence 2 sides and one angle proved so triangles are equal
The postulate that can be used to prove that triangle QXP and triangle SXR are congruent to each other is: SAS Congruence Theorem,
Recall:
Two triangles are congruent by the Side-Angle-Side Congruence Theorem, if two sides and one included angle of one triangle are congruent to two sides and the corresponding included angle in the other triangle.Since X is a midpoint of QS and RP, therefore:
[tex]PX \cong RX\\\\QX \cong SX\\[/tex]
Also,<PXQ = <SXR (vertical angles are congruent)
Thus, triangle QXP and triangle SXR are congruent by SAS.Therefore, the postulate that can be used to prove that triangle QXP and triangle SXR are congruent to each other is: SAS Congruence Theorem,
