Answer:
The number of packs is 5.
Step-by-step explanation:
Let the number of juicy packs of gum bought by Marisol be represented by n.
Adeline bought 8 packs of Fun gum with each pack containing 7 pieces of gum.
Total number of gums has Adeline = 8 x 7
= 56
Total pieces of gum has Marisol = n x 9
= 9n
Given that Adeline has 11 more pieces of gum than Marisol, thus;
56 = 9n + 11
56 - 11 = 9n
45 = 9n
n = [tex]\frac{45}{9}[/tex]
n = 5
The number packs of juicy gum bought by Adeline is 5 and total pieces of his gum is 45.

A class has 30 students. 18 are boys. what id the ratio of boys to girls? (you must simplify)
Answer:
number of students =30
boys =18
girls =30-18=12
therefore,the ratio of boys :girls
=18:12
then simpilyfing, =3:2
The ratio of the number of boys to girls in the class is 3 : 2
Total number of students = 30
Number of boys = 18
Nunber of girls = 30 - 18 = 12
The ratio of boys to girls :
Number of boys : Number of girls 18 : 12Simplify to lowest term :
Divide both sides by 63 : 2Therefore, the ratio of boys to girls is 3 : 2

What is the solution to the inequality 7<=-3x-4
Answer:
The nearest option is -3 (negative 3)
So, Option B is correct.
Step-by-step explanation:
We need to solve the inequality [tex]7 \leq -3x-4[/tex]
Solving:
Step 1: Switching sides of inequality and reversing the inequality
[tex]-3x-4\geq 7[/tex]
Step 2: Adding 4 on both sides
[tex]-3x-4+4\geq 7+4\\-3x\geq 11[/tex]
Step 3: Dividing both sides by -3 and reversing the inequality
[tex]\frac{-3x}{-3}\leq \frac{11}{-3} \\x\leq -3.6\\[/tex]
The nearest option is -3 (negative 3)
So, Option B is correct.

Answer:
8. The coordinates (0,0) represent the fact that when 0 minutes has passed, the horses have gone 0 miles because they hadn't started yet.
9. From the graph, it looks like horse A takes 4 minutes and horse B takes 2.5 minutes (aka 2 minutes and 30 seconds) to travel 1 mile.
10. For A: y = (1/4)x
For B: y = (2/5)x
11. For A: 3 miles
For B: (24/5) miles, or 4 and (4/5) miles.
12. Can't see the entire problem sorry.
Step-by-step explanation:
9. You find this by going to y=1 and look towards the right till you find the point the line intersects with y=1. Then find the x value by finding the corresponding number on the x axis.
10. A linear function will look something like this: y = mx+b, where y is the y value, x is the x value, m is the slope, and b is the y-intercept. Since both lines start from 0, you don't have to write the y-intercept since there's no point in writing +0. To find slope, you find delta y over delta x. Basically just find the difference of two y values and the difference of two x values from the same coordinate in the same order. I know that sounds really confusing but your teacher will probably teach this later on.
11. x represents the time, so just substitute x as 12 in the equation.
Jasmin can walk 1/4 mile every 1/5 hour. At this rate, how far can Jasmin
walk in one hour?
Answer:
hope this helps :)
Step-by-step explanation:
Since we know how far she can walk in 1/5 (one fifth) of an hour, if we multiply this distance by 5, we will find out how far she can walking in 5/5 (five fifths) of an hour, or to be clear: in one hour.
So, 5 x 1/4 miles = 5/4 or 1.25 miles per hour
Jazmeen can walk 1.25 miles in one hour.

The difference between 20th and 40th term is 40. Find the 100th term if the second
term is 2.
Answer:
198

t40-t20=a+39d-(a+19d)=40
or,20d=40
or,d=2
Now ,putting the value of d in equation 3,we get,
a=0
t100=a+99d

What is Unitary method?
In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.
Given that,
The price of 8 tokens is $4.40.
In order to find the cost for 19 tokens the unitary method is used as,
The cost for 1 token = $4.40/8
= $5.5
So, the cost for 19 tokens is 19 × 5.5 = $104.5
Hence, the cost for 19 tokens is $104.5.

Simplify the following:
x^2 + 6 x + 3 + 4/x
Put each term in x^2 + 6 x + 3 + 4/x over the common denominator x: x^2 + 6 x + 3 + 4/x = x^3/x + (6 x^2)/x + (3 x)/x + 4/x:

Which equation is equivalent to 7-2(3x+4)=8x
A -6x+15=8x
B-6x-1=8x
C15x+20=8x
The equation that is equivalent to the expression 7-2(3x+4)=8x is
-6x - 1 = 8x.
Option B is the correct answer.
We have,
To find the equation that is equivalent to 7-2(3x+4)=8x, simplify the given equation by applying the distributive property and combining like terms.
7 - 2(3x + 4) = 8x
First, distribute the -2 to the terms inside the parentheses:
7 - 6x - 8 = 8x
Combine like terms:
-6x - 1 = 8x
Thus,
The equation that is equivalent to the expression 7-2(3x+4)=8x is
-6x - 1 = 8x.
