7 months
Leanna has been saving for 7 months to have the balance of $450.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as linear equation in one variable.
Let's suppose the Leanna has been saving the money for 'x' months
It means total months = x
Intial balance = $100
Each month she deposit = $50
After x months she will have = $450 (with initial balance)
We can frame a linear equation in one variable such that:
50x = 450 - 100 (without initial balance)
50x = 350 (divide by 50 on both sides)
x = 7 months
Thus, Leanna has been saving for 7 months to have the balance of $450.

Saige's spaceship traveled 588 588588 kilometers ( km ) (km)left parenthesis, start text, k, m, end text, right parenthesis in 60 6060 seconds ( s ) (s)left parenthesis, start text, s, end text, right parenthesis. Determine whether or not each spaceship trip below has the same speed as Saige's spaceship. Has the same speed as Saige's spaceship Does not have the same speed as Saige's spaceship 441 km 441km441, start text, k, m, end text in 45 s 45s45, start text, s, end text 215 km 215km215, start text, k, m, end text in 25 s 25s25, start text, s, end text 649 km 649km649, start text, k, m, end text in 110 s 110s110, start text, s, end text
Answer:
The first ship has the same speed as Saige's ship while the second and third do not have the same speed.
Step-by-step explanation:
d = Distance traveled by Saige's spaceship = 588 km
t = Time taken = 60 seconds
Speed is given by
[tex]s=\dfrac{d}{t}\\\Rightarrow s=\dfrac{588}{60}\\\Rightarrow s=9.8\ \text{km/s}[/tex]
The other ships
[tex]s=\dfrac{441}{45}=9.8\ \text{km/s}[/tex]
[tex]s=\dfrac{215}{25}=8.6\ \text{km/s}[/tex]
[tex]s=\dfrac{649}{110}=5.9\ \text{km/s}[/tex]
So, the first ship has the same speed as Saige's ship while the second and third do not have the same speed.

write the equation for a line that goes through the points 0,7 and 9,2
100 points please answer
Answer:
y=-5/9x+7
Step-by-step explanation:
1. Use the two points and plug them into the slope formula to figure out the slope.
y2-y1/x2-x1
2-7/9-0 = -5/9
2. Pick one of the coordinates and use the x and y points and the slope to put them into point-slope form
y-y1=m(x-x1)
y-7=-5/9(x-0)
3. Distribute and simplify.
y-7=-5/9x-0
y=-5/9x+7
Lauren Petus paid $27 for a dress that was 10% off the list price. What was the list price of the dress?
Help me guys :)))))6
Answer:
i think its a no
Step-by-step explanation:
[tex]x-9y=12[/tex]
Coordinate Points ↝ (3,-1)
↝ If you want to check if the equation is true with (3,-1).
Substitute both x = 3 and y = -1 in the equation.
[tex]3-9(-1)=12\\3+9=12\\12=12[/tex]
The equation is true therefore,
The point does make it true.
Marcos is making bags of trail mix for hocking club he will use 22 ounces of walnuts 10.1 ounces of almonds and 26.4 ounces of cashews this amount makes 25 bags of trail mix. How many ounces are in each bag?
Answer:
2.34 ounces per bag
Step-by-step explanation:
Marcos is making bags of trail mix for hocking club he will use this amount makes 25 bags of trail mix.
The total ounces of nuts:
22 ounces of walnuts + 10.1 ounces of almonds + 26.4 ounces of cashews
= 58.5 ounces of nuts
25 bags = 58.5 ounces
1 bag = x ounces
x = 58.5 ounces/25 bags
x = 2.34 ounces per bag

Line segment AB represents 20% of a longer line segment.What is the length of the longer line segment that is 100%
Answer and explanation:
If line segment AB is 25% then it is 25/100 or 1/4 of the longer line segment that is 100%
Let's assume the line segment AB is 8 inches in length(it is one quarter of the whole), then the longer line segment which is 100% will be 4 times line AB
4×8= 32 inches
Therefore if line segment AB is 8 inches long then the full length/ longer line will be 32 inches

If the sales tax in your city is 13.6% and an item costs $16 before tax how much tax would you pay on that item round the nearest hundreth or cent.
Answer:
$2.72
Step-by-step explanation:
To calculate the amount to be paid as tax, we simply find 13.6% of the amount before tax
Mathematically, that would be;
13.6/100 * 16 = $2.716
To the nearest hundredth is $2.72

Option C. [tex]98^{\circ}[/tex]
Step-by-step explanation:
[tex]\angle DAB + \angle BAC = 180[/tex] (the two angles sum to the angle of a straight line: [tex]180^{\circ}[/tex])
[tex]122+\angle BAC = 180[/tex]
[tex]\angle BAC = 180-122[/tex]
[tex]=58^{\circ}[/tex]
[tex]24+58+x = 180[/tex] (sum of interior angles of triangle is [tex]180^{\circ}[/tex])
[tex]82+x=180[/tex]
[tex]x=98^{\circ}[/tex]
∴ Option C is correct.

katrina wants to earn $600 this week in commission what is the minimum amount she needs sell in order to earn $600 if she earns a 7.5% commission on everything she sells
Answer:
$8,000
Step-by-step explanation:
Let minimum amount she needs to sell = x
Commission rate = 7.5%
Amount of commission = $600
7.5% of x = 600
7.5/100 * x = 600
0.075 * x = 600
0.075x = 600
x = 600/0.075
= 8,000
x = $8,000
The minimum amount she needs to sell in order to earn $600 if she earns a 7.5% commission on everything she sells is $8,000
