Joshua deposited
(a). $12.85 in coins
(b). $77.14 in checks
Linear equation in one variable?
The linear equation in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution.
According to the given question
Joshua deposited checks worth six times the value of the coins he deposited.
Let Joshua deposit the value of coins be x. Then the value of x will be 6x
There is total deposit of $90.
⇒ x + 6x = 90
⇒ 7x = 90
⇒ [tex]x = \frac{90}{7}[/tex] =$12.85
Therefore,
[tex]6x = \frac{90(6)}{7} =\frac{540}{7}[/tex] = $77.14
Hence, he deposit total $12.85 in coins and $77.14 in checks.

petrol on one day and 45 litres of petrol on the
next day. If the cost of petrol is * 54 per litre,
the amount spent on petrol in these two days
9. A dairy supplies 40 litres of milk in the morn
and 50 litres of milk in the evening. If the

rupees.
8)
Petrol filled on Monday = 40 liters
Petrol filled on next day = 50liters
Total petrol filled = 90liters
Now, Cost of 1 liter petrol = Rs. 44
Cost of 90 liters petrol = 44 x90
= 44 x (100 – 10)
= 44 x 100 – 44 x10
= 4400 – 440
= Rs. 3960
Therefore, he spent Rs. 3960 on petrol.9
9)
Milk supplied in morning =40 liters
Milk supplied in evening =50 liters
Total milk supplied in one day = 90 liters
Cost of 1 litre milk =24 rupees
Cost of 90 liters milk=24 ×90
=2,160 ruees.

What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
At a dinner party with an equal number of adults and children, adults are seated at tables of exactly 8, and children are seated at tables of exactly 18.
Let 'x' and 'y' be the number of tables for adults and children. Then we have
8x = 18y
x / y = 18 / 8
x / y = 9 / 4
The minimum number of children attending the dinner party will be given as,
⇒ 4 x 18

Jenn swam ⅕ mile in ¼ hour. What is her unit rate in miles per hour?
Answer:
1/2 mile/1/5 hour = 5/2 mph = 2 1/2 mph
Step-by-step explanation:
Answer:
0.80mph
Step-by-step explanation:
If 1/5 = 1/4, then:
she swims 1/5 miles for every 1/4 (fourth) of an hour
per hour means 1 hour
we must covert 1/4 to 4/4 (one mile)
1/4 × 4/1 = 4/4
if we multiply by 4/1 to get to 4/4, then we must also multiply by 4/1 for 1/5 miles
1/5 × 4/1 = 4/5
Her unit rate in miles per hour is 4/5 per 1 miles, or 0.80mph
*0.80 = 4/5 because 4 × 20 = 80 and 5 × 20 = 100; 80/100 = 0.80*
Junior Achievement USA and the Allstate Foundation surveyed teenagers aged 14 to 18 and asked at what age they think they will become financially independent. The responses of 944 teenagers who answered this survey question as follows:

28 or older 62
Consider the experiment of randomly selecting a teenager from the population of teenagers aged to 14 to 18.
Required:
a. Compute the probability of being financially independent for each of the four age categories.
b. What is the probability of being financially independent before the age of 25?
c. What is the probability of being financially independent after the age of 24?
Answer:

(b) 0.68
(c) 0.32
Step-by-step explanation:

16 to 20 151
21 to 24 487
25 to 27 244
28 or older 62
Total 944
(a)
Compute the probability of being financially independent for each of the four age categories as follows:
[tex]P(\text{16 to 20})=\frac{151}{944}=0.159958\approx 0.16\\\\P(\text{21 to 24})=\frac{487}{944}=0.515890\approx 0.52\\\\P(\text{25 to 27})=\frac{244}{944}=0.258475\approx 0.26\\\\P(\text{28 or older})=\frac{62}{944}=0.065678\approx 0.06[/tex]
(b)
Compute the probability of being financially independent before the age of 25 as follows:
P (Financially Independent before 25) = P (16 to 20) + P (21 to 24)
= 0.16 + 0.52
= 0.68
Thus, the probability of being financially independent before the age of 25 is 0.68
(c)
Compute the probability of being financially independent after the age of 24 as follows:
P (Financially Independent after 24) = P (25 to 27) + P (28 or older)
= 0.26 + 0.06
= 0.32
Thus, the probability of being financially independent after the age of 24 is 0.32.

find the equation of the linear function represented by the table below in slope-intercept form. picture of table is below
Answer:
y = 3x + 2
Step-by-step explanation:
First you want to know what the slope intercept form is. y = mx + b. Now take two points from the table and put them in the equation [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] and get the slope of 3. Now we have y = 3x + b. To find b we need to plug in any point into the equation. I chose (-1, -1). -1 = 3(-1). Solve and you get 2. Now we are left with y = 3x + 2
The equation of the line is given by: [tex]y = 3x + 2[/tex]
----------------------------
The equation of a line, in slope-intercept formula, has the following format:
[tex]y = mx + b[/tex]
In which
m is the slope, that is, how much y changes when x changes by 1.b is the y-intercept, that is, the value of y when x = 0.----------------------------
Given two points (x,y), the slope is the change in y divided by the change in x.We have points (-1, -1) and (3,11). Thus:[tex]m = \frac{11 - (-1)}{3 - (-1)} = \frac{12}{4} = 3[/tex]
Then
[tex]y = 3x + b[/tex]
----------------------------
Point (-1,-1) means that when [tex]x = -1, y = -1[/tex], and we use this to find b.
[tex]y = 3x + b[/tex]
[tex]-1 = 3(-1) + b[/tex]
[tex]b = -1 + 3 = 2[/tex]
Thus
[tex]y = 3x + 2[/tex]

A truck driver earns $51.20 driving an 80-mile route. The driver’s next route is 120 miles long and is billed at the same rate.
How much does the driver earn on this next route?
Answer:
$76.80
Step-by-step explanation:
120/80 equals how many times the next route is larger than the first one. Which is 1.5 times larger.
Take the first earning of 51.20 and multiply by 1.5 to get 76.80
120/80=1.5
51.20*1.5=76.8
On the next route the truck driver earns $76.80.
Answer:
The truck driver will be making $76.80 on his next route.
Step-by-step explanation:
First, you calculate the amount of money he makes per mile by dividing $51.20 by 80 miles. Then you take that pay rate, and multiply by 120 miles.

The area of a square is 36 square inches. What is the perimeter of half the square?
The formula for the perimeter of a square is P = 4s, where s is the length of one of the four (4) congruent sides of the square.
The formula for the area of a square is A = s², and we're given that the area of a square, whose perimeter we're trying to find, is 36 sq. units; therefore, we have:
A = s²
36 sq. units = s²
√(36 sq. units) = √s²
6 units = s (Note: We used the positive square root (6) rather than the negative square root (-6) since you physically can't have a negative length!)
Therefore, ...
P = 4s
P = 4(6 units)
P = 24 units is the perimeter of a square whose area is 36 square units

Write an equation for the line that goes through the point (7,1) and has a slope of -1
Answer: y = -x + 8
Step-by-step explanation:
Use the slope given and Substitute the y and x-values from the given coordinate into the equation and solve for b
y = mx + b
1 = -1(7) + b
1 = -7 + b
8 = b
Rewrite the equation without the y and x values, substitute the value of b
