Solve 1. At a concert, a band sold t-shirts for $18 and hats for $12. They sold 60 t-shirts and hats combined for a total of $870. How many t-shirts did they sell? How many hats?
Answer:
25 t-shirts and 35 hats were sold
Step-by-step explanation:
Here, we want to calculate the number of hats and the number of t-shirts sold.
Let the number of hats be h and the number of t-shirts be t
The sum of both is 60;
Mathematically;
h + t = 60 •••••••••••(i)
The total revenue from selling h hats at $12 per one is 12 * h = $12h
The total revenue from selling t t-shirts at $18 per one is 18 * t = $18t
So the addition of this gives the total;
12h + 18t = 870 ••••••••(ii)
From i, h = 60-t; substitute this into ii
12(60-t) + 18t = 870
720 -12t + 18t = 870
720 + 6t = 870
6t = 870 -720
6t = 150
t = 150/6
t = 25
From the substitution;
h = 60-t
h = 60-25
h = 35
Answer:
48 hats

Jennifer is saving money to buy a bike. The bike costs $246. She has $138 saved, and each week she adds $18 to her savings.
How long will it take her to save enough money to buy the bike?
Answer: 8 weeks
explanation: 125 + 15x = 245
You then have to subtract 125 from both sides so we can isolate our variable which will give us 15x = 120 . Divide 15 from both sides : 15x/15 = 120/15 which will give us x = 8.
Formulae
The formula for working out the amount of
pasta, in grams, for a meal is
Amount of pasta=125 x number of people
Work out the amount of pasta needed for
A) 2 people
B) 10 people
Answer:
A) 250
B) 1250
Step-by-step explanation:
Amount = 125 x no. People
A) amount = 125 x 2 =250g pasta
B) amount = 125 x 10 =1250g pasta.

- Suppose Q is the midpoint of PR. Use the information to find the missing value. PQ = 3x + 14 and QR = 7x - 10; Find x.
Answer:
x =6
Step-by-step explanation: Q is the midpoint of PR.
Therefore PQ = QR
3 x + 14 = 7 x -10
-14 -14
3 x = 7 x-24
-7x -7x
-4x = -24 Divide both sides by -4
x = 6
The value of x for PQ = 3x + 14 and QR = 7x - 10 is 6 units.
What is midpoint of line segment?
The midpoint divides the line segment into two equal parts.
It is given that Q is the midpoint of PR which implies Q will divide PQ into two equal parts that is PQ (3x+14) equals QR (7x-10). now calculating x value :
[tex]\begin{aligned}PQ&=QR\\3x+14&=7x-10\\7x-3x&=14+10\\4x&=24\\x&=6\end{aligned}[/tex]
Therefore, the value of x for PQ = 3x + 14 and QR = 7x - 10 is 6 units.

Solve the equation for x.
1/3 (6x - 15) = 1/2 (10x-4)
Answer:
x = - 1Step-by-step explanation:
[tex] \frac{1}{3} (6x - 15) = \frac{1}{2} (10x - 4)[/tex]
Expand the terms in the bracket
That's
[tex] \frac{1 }{3} \times 6x + \frac{1}{3} ( - 15) = \frac{1}{2} (10x) + \frac{1}{2} ( - 4) \\ 2x - 5 = 5x - 2[/tex]
Subtract 5x from both sides
[tex]2x - 5x - 5 = 5x - 5x - 2 \\ - 3x - 5 = - 2[/tex]
Add 5 to both sides
[tex] - 3x - 5 + 5 = - 2 + 5 \\ - 3x = 3[/tex]
Divide both sides by - 3
[tex] \frac{ - 3x}{ - 3} = \frac{3}{ - 3} [/tex]
We have the final answer as
x = - 1Hope this helps you

Write the equation of the line, with the given properties, in slope-intercept form.
Slope = -2, through (-4,6)
Answer:
y= -2x -2
Step-by-step explanation:
slope-intercept form:
y= mx +c, where m is the gradient and c is the y-intercept.
Given that the slope is -2, m= -2.
Susbt. m= -2 into the equation:
y= -2x +c
To find the value of c, substitute a pair of coordinates.
When x= -4, y= 6,
6= -2(-4) +c
6= 8 +c (expand)
c= 6 -8 (-8 on both sides)
c= -2 (simplify)
Thus, the equation of the line is y= -2x -2.

100 points! Find the slope of the image.
Answer:
5/2
Step-by-step explanation:
We can use the slope formula
m = (y2-y1)/(x2-x1)
A has points ( -2,0) and (0,5) as points on the line
m = ( 5-0)/( 0 - -2)
( 5-0)/( 0 +2)
= 5/2
The lines B and C are parallel so they have the same slope 5/2
Find the common difference of the arithmetic sequence. 6, 9.4, 12.8, 16.2, . . .
Answer:
The answer is 3.4Step-by-step explanation:
The sequence above is an arithmetic sequence
So in order to find the common difference subtract the previous term from the next term
So we have
Taking 9.4 and 6
That's
9.4 - 6 = 3.4
Taking 12.8 and 9.4
12.8 - 9.4 = 3.4
Taking 16.2 and 12.8
16.2 - 12.8 = 3.4
Since the common difference is the same for any of the terms taken , the common difference is 3.4
