Gavin is saving up to buy a new phone.
He already has $100 and can save an additional $7 per week using money from his after-school job
Let us assume that he worked for 'w' weeks
The amount earned for 'w' weeks = 100 + 7w
Hence, the required expression is 100 + 7w
The total amount saved in 10 weeks = 100 + 7(10) = $ 170
Therefore,
The total money would Gavin have after 10 weeks of savings is $ 170 and the required expression is 100 + 7w

What is the missing side length in this right triangle?
Answer:
15
Step-by-step explanation:
It's a right angle triangle so we can use the pythogorean theorem to solve for Hypotenuse
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
So if we apply this formula,
[tex] {9}^{2} + {12}^{2} = {c}^{2} [/tex]
[tex]81 + 144 = {c}^{2} [/tex]
[tex]225 = {c}^{2} [/tex]
[tex]c = \sqrt{225} [/tex]
[tex]c = 15[/tex]

Solve the system of linear equations by elimination,
-y - 10 = 6x
5x +y = -10
Hey again!
The solution to the given system is (0, -10)
To solve using elimination, we have to add the equations together, and the "y"s will cancel out, and then solve the equations:
5x - 10 = 6x - 10
Now solve.
Add "10" to both sides:
5x = 6x
Subtract "5x" from both sides
0 = x
Now, we plug in the solved "x" value in an equation to solve for "y".
5(0) + y = -10
y = -10
We now know that the solution to the given system is (0, -10)
Hope this helps! Have an amazing day, and remember, you've got this!!
The solution to the given system of linear equations is (0, -10) which is determined by the elimination method.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The system of linear equations is given in the question:
-y - 10 = 6x ....(i)
5x +y = -10 ....(ii)
To solve using elimination, we have to add the equations (i) and (ii) together, and the "y" will be eliminated, and then solve the equations:
⇒ 5x - 10 = 6x - 10
Add "10" to both sides of the above equation
⇒ 5x = 6x
Subtract "5x" from both sides
⇒ 0 = x
⇒ x = 0
Now, substitute the value of x = 0 in equation (ii) to solve for "y".
⇒ 5(0) + y = -10
⇒ y = -10
Therefore, the solution to the given system of linear equations is (0, -10).

You are in the buy and sell business. find out the wholesale price of an item (e.g. t-shirt, soap,toy) suppose you buy 24 pieces of that item at wholesale price. atleast at what price should you tell each item to have a 25% profit? how much will be your total profit in pesos from these items?
With explanation please!!
The wholesale price isn't given, suppose the wholesale price is $5
Answer:
$6.25 ; 1441.8 pesos
Step-by-step explanation:
Number of items purchased = 24
Wholesale price of item = x
To obtain a 25% profit, the sales price would be :
Wholesale price = wholesale price + 25% of wholesale price
(x = x + 0.25x) per unit
For 24 items :
24x + 0.25 * 24x
Unit wholesale price = 5
24(5) + 0.25*24(5)
= $150
Hence, sale price per unit will be :
$150 / 24
= $6.25
Total profit in pesos :
1 dollar = 48.06 pesos
Total profit = $150 - 24(5) = $150 - $120 = $30
$30 = (30 * 48.06) = 1441.8 pesos

A rope is tied to a tent for support as shown. Rope Support 14 TL sin What is the length of the rope?
Answer: 10ft
Step-by-step explanation:
The pole and the distance between the rope and pole make this appear as though it is a right angled triangle which means that one should be able to calculate the length of the rope by using the Pythagorean rule where:
c² = a² + b²
a = height of right angle triangle
b = length of right angle triangle
c = hypotenuse (length of rope)
c² = 6² + 8²
c² = 36 + 64
c² = 100
c = √100
c = 10 ft
Length of rope = 10ft

Lauren rented 21 of the driving range slots at a local golf course for a long drive competition. This was 30% of the total driving range slots at the golf course. How many total driving range slots are at the golf course?
Answer: 70 driving range slots.
Step-by-step explanation:
Lauren rented 21 driving range slots and this represented 30% of the total driving range slots available.
To calculate the total, assume the total is x.
30% * x = 21
0.3x = 21
x = 21/0.3
x = 70 driving range slots.

Merry has a pipe that she wants to cut into 4 pieces. If the pipe is 26 2/3 feet long, how long should she cut each piece?
Answer: 6 2/3 ft
Explanation:
1. Turn the mixed number (26 2/3) into an improper fraction by multiplying 26 by 3 and then adding 2. (26x3=78)(78+2=80=80/3)
2. Now divide 80 by the number of pieces she’s cutting (4). (80÷4=20)
3. Now divide 20 by the denominator (3) to convert it back into a mixed number. (20÷3=6 2/3)
h=(500-260)divided by 2
Answer:
h = 120
Step-by-step explanation:
The required, division of h=(500-260)divided by 2 is 120..
The division is a mathematical operation that involves distributing or sharing a quantity into equal parts. It is the inverse operation of multiplication. In division, a dividend is divided by a divisor to obtain a quotient.
h = (500 - 260) divided by 2
To solve this expression, we first perform the subtraction within the parentheses:
h = (240) / 2
Simplifying further:
h = 120
Therefore, the value of h is 120.
