52% problems are pointless i.e. 48% are NOT pointless.
Recall that 1% = 1/100.
Therefore 48% = 48/100 = 12/25.
Let x be the number of problems that are not pointless.
x/175 = 12/25
x = 84
Answer:
84
Step-by-step explanation:
According to the question
175×48%

The Econ motel charges $260 for 4 nights, how much would they charge for 7 nights?
Answer:
$455
Step-by-step explanation:
To find the answer, divide 260 by 4 to find the cost of one night. This gets us 65. Now, we multiply 65 by 7 to get 455. This means it costs $455 for 7 nights.
Answer:
$455
Step-by-step explanation:
260 divided by 4 is 64
64 times 7 is 455

A manager of a clothing store always orders 2 small T-shirts and 3 large T-shirts for
every 4 medium T-shirts. The manager plans to order 24 medium T-shirts. How
many small T-shirts and large T-shirts should the manager order? Show your work.
Answer:
12 small, 18 large
Step-by-step explanation:
x - small
y - large
z- medium
4z=2x=3y then she orders 24
24/4=6 times more than usually, so we should *6 for every x and z
24z=6*2x=6*3y
12 - x - small tshirt
18 - y - large

Solve the inequality
Answer:
x ≥ -64
Step-by-step explanation:
"3/4ths of a number is greater than or equal to -48"
3/4 of a number ≥ -48
Let's say the number is x.
(3/4)x ≥ -48
Multiply both sides by 4.
3x ≥ -192
Divide both sides by 3.
x ≥ -64

3 There are 5 times as many boys as girls in a school.
Together the school has 810 pupils.
How many boys are there?
Answer:
Number of boys = 675
Step-by-step explanation:
Given that:
There are 5 times as many boys as girls in a school.
Number of pupils in school = 810
Let,
x be the number of girls
y be the number of boys
According to given statement;
x+y=810 Eqn 1
y = 5x Eqn 2
Putting y=5x in the Eqn 1
x+5x=810
6x=810
Dividing both sides by 6
[tex]\frac{6x}{6}=\frac{810}{6}\\x=135[/tex]
Putting x=135 in Eqn 2
y = 5(135)
y = 675
Hence,
Number of boys = 675
A biologist is recording the loss of fish in a pond. He notes the number of fish, f, in the pond on June 1. On July 1 there were 63 fish in the pond, which is 52 fewer fish than were in the pond on June 1. What is the number of fish in the pond on June 1?
Which equation can be used to find the number of fish in the pond on June 1?
63−f=52
f−52=−63
f−52=63
f−63=−52
Answer:
the correct answer should be f-52=63
Step-by-step explanation:
3x + y = 15 and y = 2x
The solution, given in (x,y) form is
Answer: (3, 6)
Step-by-step explanation:
3x + y = 15
y = 2x
Using substitution:
3x + 2x = 15
5x = 15
x = 15/5
x = 3
y = 2x
y = 2 * 3
y = 6
x = 3
y = 6
= (3, 6)

If f(x) = 3x - 1 and g(x) = x + 2, find (f- g)(x).
I can’t find it
Answer:
[tex](f-g)(x)=2x-3[/tex]
Step-by-step explanation:
We are given the two functions:
[tex]f(x)=3x-1\text{ and } g(x)=x+2[/tex]
And we want to find:
[tex](f-g)(x)[/tex]
This is equivalent to:
[tex]=f(x)-g(x)[/tex]
By substitution:
[tex]=(3x-1)-(x+2)[/tex]
Simplify. Distribute:
[tex]=(3x-1)+(-x-2)[/tex]
Rearrange:
[tex]=(3x-x)+(-1-2)[/tex]
Therefore:
[tex](f-g)(x)=2x-3[/tex]
Circle geometry please help,
Answer:
7. Inscribed angle
Step-by-step explanation:
7. Inscribed angle
8.
y° = 70°
z° = 140°
8. y° and 70° are the measures of the angles subtended in the same arc. So, they would be equal.
Therefore, y° = 70°
Measure of central angle is two times the measure of the inscribed angle.
Therefore,
z° = 2* 70° = 140°
At the end of school, Josh's teacher handed out 27 coupons for bowling during the summer to each student. The third week of

32. The price of a box of tarts is $1 cheaper than that of a loaf of bread. If 3 times the price of a
loaf of bread is $29.5 more than half of the price of a box of tarts, find the price of a box of
tarts.
A. $4.3
B. $7.7
C. $9.84
D. $13
Answer: $8.60
Step-by-step explanation:
Let the price of a bread = x
Let the price of a tarts = x - 1
If 3 times the price of a loaf of bread is $29.5 more than half of the price of a box of tarts. This can be represented as:
3 × x = 1/2 × (1 - x) + 29.5
3x = 0.5 - 0.5x + 29.5
3x + 0.5x = 29.5 + 0.5
3.5x = 30
x = 30/3.5
x = 8.6
