a coach bought three soccer balls on sale. they normally sell for $26 each. they were on sale for $7 off the original price. the total tax on the ball was $4 . the expression represents the total amount paid. Then explain how to use the order of operations to find the total amount the coach paid for the soccer balls.
Answer:
The coach paid $69 on the three soccer balls
Step-by-step explanation:
If the coach bought 3 soccer balls for 26$, minus the $7 on each, plus the $4 tax on each, the expression would be:
3 × (26 - 7 + 4)
We put the addition and subtraction in parentheses because of PEMDAS. PEMDAS say we must solve for whatever is in the parentheses first, then exponents (there are none in the expression), ans then multiplication. If those numbers were not in parentheses, the answer would look completely different as we would multiply before subtracting and adding. We must find the total amount each ball cost first:
26 - 7 + 4 = 23
Each ball cost $23
If the coach bought 3 balls for $23 each, we have to multiply the two numbers:
3 × $23
$69

A drink is mixed in the ratio
lemonade : orange : cranberry = 6 : 3 : ?
If the fraction for cranberry juice is 3/12, what would be the missing number in the ratio?
Answer:
3
Step-by-step explanation:
Drink mix ratio:
Lemonade : Orange : Cranberry
6 : 3 : C
Fraction of Cranberry juice = [tex]\frac{3}{12}[/tex]
Sum of the ratio = 6 + 3 + C = 9 + C
Fraction of Cranberry;
[tex]\frac{C}{9 + C}[/tex] = [tex]\frac{3}{12}[/tex]
3(9 + C) = 12C
27 + 3C = 12C
27 = 12C - 3C
9C = 27
C = 3
The missing number will be 3
2(y+2)-y=3(y-1)+9 I am solving for y
Answer:
y = -1
Step-by-step explanation:
Step 1: Write equation
2(y + 2) - y = 3(y - 1) + 9
Step 2: Solve for y
Distribute: 2y + 4 - y = 3y - 3 + 9Combine like terms: y + 4 = 3y + 6Subtract y on both sides: 4 = 2y + 6Subtract 6 on both sides: -2 = 2yDivide both sides by 2: -1 = yRewrite: y = -1Step 3: Check
Plug in y to verify it's a solution.
2(-1 + 2) - (-1) = 3(-1 - 1) + 9
2(1) + 1 = 3(-2) + 9
2 + 1 = -6 + 9
3 = 3

What is y=3x+13 in standard form?
Answer:
3 x − y = − 13
Step-by-step explanation:
Any equation that relates the first power of x to the first power of y produces a straight line on an x-y graph. The standard form of such an equation is Ax + By + C = 0 or Ax + By = C. When you rearrange this equation to get y by itself on the left side, it takes the form y = mx +b. This is called slope intercept form because m is equal to the slope of the line, and b is the value of y when x = 0, which makes it the y-intercept. Converting from slope intercept form to standard form takes little more than basic arithmetic.
TLDR:
To convert from slope intercept form y = mx + b to standard form Ax + By + C = 0, let m = A/B, collect all terms on the left side of the equation and multiply by the denominator B to get rid of the fraction.
Answer:
3x - y = -13
Step-by-step explanation:
y = mx + b
(This is the slope intercept form)
We want to change it to standard form, which is:
Ax + By = C
We want to rearrange as many of the numbers as we can, without actually changing the problem!
Ax = 3x
By = y
C = 13
So we must move the numbers from one side to another.
Whatever you do to one side, you do to the other.
y = 3x + 13
-3x + y = -3x - y
--------------------
-3x + y = 13
Since we can't have our "Ax" as a negative multiply everything by -1
-1[-3x + y = 13]
3x - y = -13
That is your answer.

Parallel to y=-3x+4, x-intercept at 4
Answer:
y = -3x + 12
Step-by-step explanation:
The slope of parallel line is the same as the original line.
If the x-intercept is 4, this as a point can be stated as (4, 0)
We can now solve for the y-intercept.
y = -3x + b
0 = -3(4) + b
0 = -12 + b
12 = b
Put everything we solved for back into the formula [ y = mx + b ]
y = -3x + 12

Hayley and Maxwell are jogging on a track. Hayley jogs 3/4 mile in 1/6 hour. Maxwell jogs 2/3 mile in 2/15 hour. Who is faster?
Maxwell runs faster than Hayley
In order to determine who runs faster, the average speed has to be determined
Average speed is total distance travelled divided by total time travelled.
Average speed = Total distance / Total time
Hayley's average speed = [tex]\frac{3}{4}[/tex] ÷ [tex]\frac{1}{6}[/tex]
= [tex]\frac{3}{4}[/tex] x 6 = [tex]\frac{9}{2} = 4\frac{1}{2}[/tex] miles / hour
Maxwell's average speed = [tex]\frac{2}{3}[/tex] ÷ [tex]\frac{2}{15}[/tex]
[tex]\frac{2}{3}[/tex] x [tex]\frac{15}{2}[/tex] = 5 miles / hour
Maxwell runs faster because he has a higher average speed when compared with Hayley

The graph below shows how much money you have in savings each week. Use
this graph to answer questions (a – g).
a. According to the graph how much money did you start with in your savings?
b. How much money will you have after 5 weeks of saving?
Answer:
Step-by-step explanation:
a). Since starting point of the line is (0, 50),
Therefore, I started with the saving of $50.
b). Since endpoint of the segment is (5, 175),
Money with me after 5 weeks will be $175.
c). Let the equation of the line given in the graph is,
y - y' = m(x - x')
Where (x', y') is a point lying on the graph.
And 'm' is the slope of the line.
Slope of the line = [tex]\frac{175-50}{5-0}[/tex]
m = [tex]\frac{125}{5}[/tex]
m = 25
Since, the line passes through (0, 50),
y - 50 = 25(x - 0)
y = 25x + 50
y = 25x + 50
For x = 6,
y = 25×6 + 50 = 200
For x = 7,
y = 25×7 + 50 = 225
For x = 8,
y = 25×8 + 50 =250
d). For x = 10 weeks,
y = 25×10 + 50 = $300
e). For x = 15 weeks
y = 25×15 + 50 = $425
f). For x = 50 weeks,
y = 25×50 + 50 = $1300
g). Equation of the line is,
y = 25x + 50

Answer:
54w-9
Step-by-step explanation:
the box to the right is -1 because you are multiplying 6w-1 by 9 (the box next to the blank one on the bottom). the other blank box below the 6w is going to be 54w since you multiply 6w and 9 to get that. therefore, 9(6w-1) is 54w-9.
In training for a swim meet, Logan swam 750 meters in 1.3 of a hour. His swimming partner , Mila swam 2.3 of Logan's distance in 1.4 of a hour. What is Logan's average swimming speed? What is Mila's average swimming speed? Compare Mila's and Logan's swimming speed.
Answer:
Step-by-step explanation:
For Logan:
Logan swam 750m
Logan distance = 750m
Time taken = 1.3×3600
Time taken = 4680
Logan average speed = distance/time
average speed = 750/4680
Logan Average speed = 0.160m/s
Mila swam 2.3 of Logan's distance
Milan distance = 1725m
Time taken = 1.4×3600
Time taken = 5040s
Milan average speed = distance/time
Milan average speed = 1725/5040
Milan average speed = 0.342m/s
Comparing Milan speed with Logan speed:
Difference in speed = 0.342-0.160
Difference in speed = 0.182m/s
This means that Milan speed is 0.182 greater than Logan speed.
