10(x-5)= -80
what is the value of the x
Answer:
x = -3
Step-by-step explanation:
10(x-5) = -80
10x - 50 = -80
10x -50 + 50 = -80 + 50
10x = -30
10x ÷ 10 = -30 ÷ 10
x = -3

A teacher purchased 20 calculators and 10 measuring tapes for her class and paid $495. Later, she realized that she didn't order enough supplies. She placed another order of 8 of the same calculators and 1 more of the same measure tape and paid $178.50.The system represents the situation
`20c+10m=495`
`8c+1m=178.50`
Find the cost of one calculator and the cost of one measure tape using one of our methods of solving systems.
Answer:
Equations are
20c + 10m = 495..............(1)
8c + 1m = 178.5.................(2)
Now , equation (2) * 10 = 80c + 10m = 1785...........(3)
So, Eq. (3) - Eq(1) =
80c + 10m - 20c - 10m = 1785 - 495
60c = 1290
c= 21.5
********************************************************
Now place the value of c in Eq (2)
So , m =6.5

Find the x- and y-intercepts of the graph of x + 5y = 6 state your answer as whole numbers or as improper fractions in simplest form
Answer:
[tex]y=-\frac{1}{5}x+\frac{6}{5}[/tex]
Step-by-step explanation:
Let's solve for x.
[tex]x+5y=6[/tex]
Step 1: Add -5y to both sides.
[tex]x+5y+-5y=6+-5y[/tex]
[tex]x=-5y+6[/tex]
Answer:
[tex]x=-5y+6[/tex]
Let's solve for y.
[tex]x+5y=6[/tex]
Step 1: Add -x to both sides.
[tex]x+5y+-x=6+-x[/tex]
[tex]5y=-x+6[/tex]
Step 2: Divide both sides by 5.
[tex]\frac{5y}{5}=\frac{-x+6}{5}[/tex]
[tex]y=\frac{-1}{5} x+\frac{6}{5}[/tex]
Answer:
[tex]y=\frac{-1}{5} x+\frac{6}{5}[/tex]

Step-by-step explanation:
If a 24oz bottle of water costs $2.35. What is the cost per ounce? Round to the nearest penny.
Answer:
10¢
Step-by-step explanation:
To find how much an ounce cost, dive 2.35 by 24.
[tex]\frac{2.35}{24} = 0.097\\[/tex]
Multiply by 100, and thus you get 9.79, or, to the nearest penny, 10 cents.

Katie wants to collect over 100 seashells. She already has 34 seashells in her collection. Each day, she finds 12 more seashells on the beach. Katie can use fractions of days to find seashells. Write an inequality to determine the number of days, d, it will take Katie to collect over 100 seashells.
Answer:
34+12x=100 12x=66 x=66/12=11/2 answer:11/2
Step-by-step explanation:
Answer:
[tex]12n+34>100[/tex]
Step-by-step explanation:
Let d be the number of days.
We have been that each day Katie finds 12 more seashells on beach, so after collecting shells for d days Katie will have 12d shells.
We are also told that Katie already has 34 seashells in her collection, so total number of shells in Katie collection after d days will be: [tex]12n+34[/tex]
As Katie wants to collect over 100 seashells, so the total number of shells collected in d days will be greater than 100.
The piecewise function h(x) is shown on the graph.
On a coordinate plane, a piecewise function has 2 lines. The first line has a closed circle at (negative 4, negative 4) and goes up to an open circle at (negative 1, 2). The second line has a closed circle at (negative 1, 3), continues horizontally to (1, 3), and then goes down to a closed circle at (4, 0).
What is the value of h(3)?
–2
–1
1
2
Step-by-step explanation/Answer:
The value for h(3) is 1.
Coordinate (3,1)
The value on h(3) is located in the last part of the piecewise function, which starts at (1,3) until (4,0). To know the exact image of h(3), we can find the function that belongs to that piece of line, and then calculated the asked value.
So, to calculate the equation, we first have to find the slope with its definition, and then we'll use the point-slope formula to find the equation:
Therefore, the coordinates is (3,1), that is, the value for h(3) is 1.

"An airplane ends up 540 miles and 20 degrees north of east from its departure point. If there was a steady wind of 30 mph from the northwest during the entire flight, then find the magnitude and direction that the plane would have gone if there had been no wind".
Answer:
vr = [tex]540[/tex]
vp = 486.22 j + 205.9 j
Theta [tex]= 22.95[/tex]
Step-by-step explanation:
The resultant velocity vr = vp + vw
vp = vector velocity of plane and
vw = vector velocity of wind
vr = vector resultant velocity
in one hour the plane travels 540 miles and hence the speed is 540 mph
Hence vr = [tex]540[/tex]
vp = 486.22 j + 205.9 j
Theta
[tex]= tan^{-1}\frac{205.9}{486.22} \\= 22.95[/tex]

what are the rules for multiplying negative numbers?
Answer:
When multiplying negative numbers, just remember 2 things. 1: 2 negative values will always give a positive value. 2: If you only have 1 negative value, your answer will also be negative. Just remember these rules and the rest is simple multiplication.
Answer:
Hi there! Your answer is down below!
Step-by-step explanation:
The rule of how to multiply negatives is simple: For a case where a negative number is multiplied by a positive, the rule above can be restated as: take the positive number, and the negative WITHOUT the minus sign, multiply them and add the inus sign to the product.

Krysta is looking for a job cutting hair. One option is self-employment at The Richmond Salon, where she would pay $474 per month to rent a station and keep all of her earnings. Another option is to work at a franchise, where she would just have to pay the salon $6 for every haircut. If she performed a certain number of haircuts every month, the amount paid to either salon would be the same. How many haircuts would that be? How much would Krysta pay?
Answer:
79 haircuts and $474
Step-by-step explanation:
The computation is shown below:
Given that
she would have to pay $474 per month
And $6 for every haircut
So, the number of haircuts would be
= $474 ÷ $6
= 79 haircuts
The amount that she have to pay is $474
The raito of chocolate covered carmels to choclate corvered cherries in my vault is 5 to 2 if i have 84 choclate covereds cherries how many choclate covered caramels do i have
Answer: 1 have 210 chocolate covered caramels
Step-by-step explanation:
step 1
The ratio of chocolate covered caramels to chocolate covered cherries in my vault is 5 to 2 which can also be written as 5:2
But the number of chocolate covered cherries =84
Total ratio is given as 5+2 = 7
Step 2
such that the total number of chocolate i had would be gotten from
Ratio of chocolate covered cherries/ total ratio x Total chocolates = Number of chocolate covered cherries. Let X = Total number of chocolates
2/7 x X = 84
x= 84 x 7 / 2 =294
Therefore The number of chocolate covered caramels= ratio of chocolate covered caramels/ total ratio x Total chocolates =
5/7 X 294= 210
Ms. Potts washed 1/4 of her laundry. Her son washed 3/7 of it. Who washed most of the laundry? How much of the laundry still needs to be washed?
Answer:
Son washed moreRemaining 9/28 of the laundryStep-by-step explanation:
Make denominators common to see the difference in fractions:
1/4 = 7/283/7 = 12/28Son washed more laundry as 12/28 > 7/28
Together they washed:
7/28 + 12/28 = 19/28 of the laundryRemaining part is:
1 - 19/28 = 28/28 - 19/28 =9/28 of the laundryStep-by-step explanation:
9/28 is your answer......
