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

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

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.

1. The product of 3 and a number increased by six is 24.1
Answer:
3x + 6 = 24.1
Step-by-step explanation:
The product of 3 and a number (x) increased (adding) by 6 is 24.1 (the result).
if y=24 when x=6, find y when x=-4.
Answer:
[tex]\huge\boxed{y=-16}[/tex]
Step-by-step explanation:
We have to note that this represents a proportional relationship. This means that every time x increases by 1, y will increase by a proportional value.
In order to solve for proportions, we can create a proportion fraction which basically puts two variables over each other. Let's put x over y.
[tex]\frac{x}{y}[/tex]
We know that in the first fraction, x=6 and y=24.
[tex]\frac{6}{24}[/tex]
And we know that x=-4 but we have an unknown y value.
[tex]\frac{-4}{y}[/tex]
We can now set these proportions equal to each other and solve for the missing y using cross products.
[tex]\frac{6}{24}=\frac{-4}{y}[/tex] [tex]y = (24 \cdot -4) \div 6[/tex] [tex]y = -96 \div 6[/tex] [tex]y = -16[/tex]Hope this helped!
1-6. Indicate whether each table or graph represents a proportional
relationship or a non-proportional relationship.
pls answer! nobody answer right and I am sick of failing this is for a mastery
Answer:
Step-by-step explanation:
Proportional relationship means,
x ∝ y
x = ky
[tex]\frac{x}{y}=k[/tex] where 'k' is the proportionality constant.
From table (1),
[tex]\frac{1}{5}=\frac{2}{9}\neq \text{Constant}[/tex]
Therefore, relationship is not proportional.
From table (2),
[tex]\frac{1}{6}=\frac{3}{18}=\text{constant}[/tex]
True.
So the relationship will be proportional.
From table (3),
[tex]\frac{\text{hours}}{\text{Miles}}= \frac{2}{110}=\frac{5}{175}=\frac{1}{55}[/tex]
Which is constant.
Therefore, relationship will be proportional.
From table (4),
[tex]\frac{\text{Hours}}{\text{Paid}}=\frac{3}{29.25}=\frac{5}{48.75}=0.103[/tex]
Which is constant for every term.
Therefore, relationship will be proportional.

Find the value of p. p − 1 = 5 p + 3p − 8
Answer:
p = 1
Step-by-step explanation:
[add like terms]
p - 1 = 8 p - 8
[add 8 to both sides]
p + 7 = 8 p
[subtract p from both sides]
7 = 7 p
[divide each side by 7]
p = 1
Answer:
P=1
Step-by-step explanation:
collecting like terms we have
p - 5p - 3p = -8 + 1
-7p = -7
divide both sides by -7
p = 1

A and B are complementary angles. If mA=(x+8)° and mB =(8x+1),
find the measure of A
Answer:
[tex]\angle A=17\textdegree[/tex]
Step-by-step explanation:
We know that A and B are complementary angles. So, they must add up to 90°. As an equation:
[tex]\angle A+\angle B=90[/tex]
Since we know their equations, substitute:
[tex](x+8)+(8x+1)=90[/tex]
Solve for x. Combine like terms on the left:
[tex]9x+9=90[/tex]
Subtract 9 from both sides:
[tex]9x=81[/tex]
Divide both sides by 9:
[tex]x=9[/tex]
So, the value of x is 9.
We want to find A. So, let's use the equation for A:
[tex]\angle A=x+8[/tex]
Substitute 9 for x:
[tex]\angle A=9+8[/tex]
Add:
[tex]\angle A=17\textdegree[/tex]
So, the measure of A is 17°.

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.

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.

Step-by-step explanation:
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
