Melinda earns $48 for every 3 lawns she mows in her neighborhood. She wants to buy a skateboard that costs $208. How many lawns will Melinda have to mow to be able to buy the skateboard?
Enter the correct answer in the box.
Answer:
13 lawns
Step-by-step explanation:
Find out how much money Melinda earns for 1 lawn mowed (variable x represents money earned):
3x = 48
Isolate the variable by dividing both sides by 3
3x ÷ 3 = 48 ÷ 3
1x = 16
x = 16
She earns $16 per mowed lawn
Set up equation to find out how many lawns she needs to mow to earn $208 (variable y represents lawns mowed):
16y = 208
Isolate the variable by dividing both sides by 16
16y ÷ 16 = 208 ÷ 16
1y = 13
y = 13
She needs to mow 13 lawns to earn $208
Answer: The answer is 13 lawns... Have a great day!

Answer:
The value of x is 9
Step-by-step explanation:
The measure of the exterior angle at a vertex of a triangle equals the sum of the measures of the two opposite interior angles to this vertex
In the given figure
∵ ∠DFG is an exterior angle at vertex F
∵ The angles of measures (5x - 7) and 89° are the opposite interior
angles to the vertex F
∴ m∠DFG = (5x - 7) + 89
∵ m∠DFG = 14x + 1
→ Substitute it in the equation above
∴ 14x + 1 = 5x - 7 + 89
→ Add the like terms in the right side
∵ 14x + 1 = 5x + 82
→ Subtract 1 from both sides
∵ 14x + 1 - 1 = 5x + 82 - 1
∴ 14x = 5x + 81
→ Subtract 5x from both sides
∴ 14x - 5x = 5x - 5x + 81
∴ 9x = 81
→ Divide both sides by 9
∴ x = 9
∴ The value of x is 9
For a scale to pass inspection, the scale's reading can vary by at most
0.1% from the actual mass of an object on the scale. A test mass has
an exact mass of 250.00 grams. In what range must the scale's reading
be for the scale to pass inspection?
Answer:
I think its 249.99 to 250.01
Step-by-step explanation:
The range of the variation for the scale will be 249.75 grams to 250.25 grams.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that for a scale to pass inspection, the scale's reading can vary by at most 0.1% from the actual mass of an object on the scale. A test mass has an exact mass of 250.00 grams.
The variation of the mass will be calculated as:-
Variation = 250 x 0.1% = ( 250 x 0.1 ) / 100 = 0.25
Higher variation = 250 + 0.25 = 250.25 grams
Lower variation = 250 - 0.25 = 249.75 grams
Therefore, the range of the variation for the scale will be 249.75 grams to 250.25 grams.

if a is 1 more than b it can be expressed as so:
a=b+1
b+1=a
b^2+1=a^2
b^2=a^2-1
b=a-1
if b if 1 then a is 2
b+1=a
-a+b=-1
a-b=1
a=2, b=1
a=b+1

An angle measures 86° less than the measure of its supplementary angle. What is the measure of each angle?
The angle if an angle measures 86° less than the measure of its supplementary angle is 133.
Supplementary angles are two angles whose measures add up to 180° .
Supplementary Angles
Let the measure of one of the supplementary angles be a .Measure of the other angle is 2 times a .So, measure of the other angle is 2a .If the sum of the measures of two angles is 180° , then the angles are supplementary.Let the angle be "x".
Its supplementary angle is "180-x"
Equation:
180 - x - x = 86
180 - 2x = 86
2x = 180 - 86
2x = 94
x = 47
Angle x = 47 degrees
supplementary angle is "180-x"
= 180 -47
= 133
Hence , If an angle is 86° smaller than its supplementary angle, the angle is 133°.

Answer:

The solution graph is also attached.
Step-by-step explanation:
Given
[tex]4\:\le \:y\:+\:2\:\le -3\left(y-2\right)+24[/tex]
as
[tex]\mathrm{If}\:a\le \:u\le \:b\:\mathrm{then}\:a\le \:u\quad \mathrm{and}\quad \:u\le \:b[/tex]
so
[tex]4\le \:y+2\quad \mathrm{and}\quad \:y+2\le \:-3\left(y-2\right)+24[/tex]
solving the intervals
as
[tex]4\le \:y+2[/tex]
[tex]y+2\ge \:4[/tex]
subtract 2 from both sides
[tex]y+2-2\ge \:4-2[/tex]
[tex]y\ge \:2[/tex]
also
[tex]y+2\le -3\left(y-2\right)+24[/tex]
[tex]y+2\le \:-3y+30[/tex]
subtract 2 from both sides
[tex]y+2-2\le \:-3y+30-2[/tex]
[tex]y\le \:-3y+28[/tex]
Add 3y to both sides
[tex]y+3y\le \:-3y+28+3y[/tex]
[tex]4y\le \:28[/tex]
Divide both sides by 4
[tex]\frac{4y}{4}\le \frac{28}{4}[/tex]
[tex]y\le \:7[/tex]
so combining the intervals
[tex]y\ge \:2\quad \mathrm{and}\quad \:y\le \:7[/tex]
Merge overlapping intervals
[tex]2\le \:y\le \:7[/tex]
Therefore,
[tex]4\le \:y+2\le \:-3\left(y-2\right)+24\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:2\le \:y\le \:7\:\\ \:\mathrm{Interval\:Notation:}&\:\left[2,\:7\right]\end{bmatrix}[/tex]
