Answer:
Step-by-step explanation:
y=mx+b b= y-intercept y-intercept=where the line crosses the y-axis m=slope slope== rise/run or slope formula, m=y2-y1/x2-x1
For example, number 1's slope is 5/3. On a graph, you would go up 5 (not in block, but in numerical value) and right 3. The y-intercept is -2. This is where your line starts on the graph.
sorry, cant help ya there buddy
Mr. Quick bought a new computer system. The regular price was $1,580, but he got a 15% discount. How much did he actually pay?
Answer:
$1343
Step-by-step explanation:
Mr. Quick bought a new computer system. The regular price was $1,580, but he got a 15% discount. How much did he actually pay?
You need to turn 15% into a decimal.
Move the decimal point to the left 2 spaces.
15 ---> 1.5 ---> 0.15
Now multiply 0.15 by $1,580.
0.15 × $1,580
Which is $237.
Now subtract $1580 - $237.
Which is $1343.
Answer:
$1580*15/100=$237that is discount rate.
$1580-237=$1343 actually pay
Simplify each expression involving signed numbers.
-7 – 2 =
12 + (-4) =
-8(-6) =
18/-3=
Answer:
-5 , 8 , 48 , -6
Step-by-step explanation:
-7- -2 = -5
This complies with the rule that 2 negatives make a positive.
12 + (-4) = 8
You just ignore the brackets.
-8(-6) = 48
The -8 next to the bracket with no symbol means you need to multiply, and again 2 negatives make a positive.
18/-3 = -6
As the 18 is not negative, but -3 is, the answer is also a negative because one negative and one positive make a negative!
Hope this helps and have a good day!
2(3y + 7 + 5) = 196 - 16
what’s the value of y?
And tell me how you know this and why or Y ahahahahahaha
Answer:
y=60
Step-by-step explanation:
196 - 16 = 180
7 + 5 = 12
12 + 3y = 15y
2 * 15y = 30y
180 ÷ 30 = 60
y = 60
Answer:
y=26
Step-by-step explanation:
Let's solve your equation step-by-step.
2(3y+7+5)=196-16
Step 1: Simplify both sides of the equation.
2(3y+7+5)=196-16
(2)(3y)+(2)(7)+(2)(5)=196+-16 (Distribute)
6y+14+10=196+-16
(6y)+(14+10)=(196=-16) (Combine Like Terms)
6y+24=180
Step 2: Subtract 24 from both sides.
6y+24-24=180-24
6y=156
Step 3: Divide both sides by 6.
6y/6 = 156/6
y=26

There are 31 girls and 25 boys in the marching band. When the band marches, they are in 7 rows. How many people are in each row?
Answer:
there are 8 people in each row
Step-by-step explanation:
(31+25) ÷ 7
Answer:
8 people
Step-by-step explanation:
Since there are 31 girls and 25 boys, you can add them to get 56 people total.When they march, there are 7 rows. So, you can divide 56 by 7, and get 8.Therefore, you have 8 people in each row.Leroi and Sylvia both put $100 in a savings account. Leroi decides he will put in an additional $10 each week. Sylvia decides to put in an additional 10% of the amount in the account each week.

(219,379.01 - x) / x = .3321
Answer:x = 164686.592598
Step-by-step explanation:
219379.01−x/x = 0.3321
−x+219379.01/x = 0.3321
Step 1: Multiply both sides by x.
−x+219379.01≈0.3321x
−x+219379.01 − 0.3321x = 0.3321x−0.3321x (Subtract 0.3321x from both sides)
−1.3321x + 219379.01 = 0
−1.3321x + 219379.01 − 219379.01 = 0 − 219379.01 (Subtract 219379.01 from both sides)
−1.3321x = −219379.01
−1.3321x/−1.3321 = −219379.01/−1.3321
(Divide both sides by -1.3321)
x = 164686.592598
Answer:
164,686.59
Step-by-step explanation:
Carry out the division, then solve for x.
(219,379.01 - x) / x = .3321 . . . . . given
219,379.01/x -1 = 0.3321
219,379.01/x = 1.3321 . . . . add 1
219,379.01/1.3321 = x ≈ 164,686.59 . . . . multiply by x/1.3321
Rounded to 8 significant digits, the value of x is 164,686.59.

A local gaming store bought a gaming console for $90. The gaming store sold the console, and the percent markup was 162%. What is the selling price?
The selling price is: $_________
Skip to navigation
Answer:
$145.80
Step-by-step explanation:
The original cost of the product was $90. There was a 162% markup. In order to get the selling price, I like to take away 100 percent and simply add original price+(original price*62%). After taking away 100%, I am left with 62%. I then multiply the original cost ($90) by the remaining percent (62%), getting 55.8. Following the steps that I originally wrote, I now add 90 to 55.8, getting 145.8.
Answer:$145.80
Step-by-step explanation:
A phone company advertises a new plan in which the customer pays a fixed amount of $ 25 per month for unlimited calls in the country and $ 0.10 per minute for international calls . Write an equation for the monthly payment a customer pays according to the new plan . Use y for monthly payment , and x for international minutes.
Type the equation in the form y=ax+b without using any spaces. Write any decimals in the form 0.00
Answer:
y = a(.10) + 25
Step-by-step explanation:
Using the equation y = ax + b.
"$25 per month for unlimited calls in the country and $0.10 per minute for international calls."
The word "per" indicating that you are multiplying this.
The only variables being multiplied are a and x.
Thus, a is the amount of minutes, x is the cost of international calls and b is the cost of unlimited calls.
