Answer:
[tex]y = - 4[/tex]
Step-by-step explanation:
subtract three from both sides and simplify 35 - 3 to 32
-8y = 32
divide by -8
[tex]y = - \frac{32}{8} [/tex]
simplify
y = -4
Answer:
-4
Step-by-step explanation:
-8y + 3 = 35
-8y + 3 - 3 = 35 -3
-8y = 32
-8y/-8 = 32/-8
y = -4
A collection of dimes and nickels has a total value of two dollars and contains 28 coins. How many dimes are there in the collection?
A.)14 dimes
B.)8
C.)12
D.)10
Answer:
12 dimes
Step-by-step explanation:
Let :
Dime = x
Nickel = y
Dime is worth 10 cent = $0.1
Nickel is worth 5 cent = $0.05
x + y = 28 - - - (1)
0.1x + 0.05y = 2 - - - (2)
From (1)
x = 28 - y
0.1(28 - y) + 0.05y = 2
2.8 - 0.1y + 0.05y = 2
2.8 - 0.05y = 2
2.8 - 2 = 0.05y
0.8 = 0.05y
y = 0.8 / 0.05
y = 16
x = 28 - 16
x = 12

An electrician charges y amount to work x hours on a job. The electrician charges a $50 service fee and $30 per hour. His income per job can be modeled using a linear function. The electrician works maximum of 20 hours on any job. What is the range of values for one job?
Answer:
The range of values from one job is between $50 and $650.
Step-by-step explanation:
An electrician charges y amount to work x hours on a job. The electrician charges a $50 service fee and $30 per hour.
This means that his earnings in a job can be modeled by the following function:
[tex]y = 30x + 50[/tex]
The electrician works maximum of 20 hours on any job. What is the range of values for one job?
Minimum, he works 0 hours, and earns:
[tex]y(0) = 30(0) + 50 = 50[/tex]
Maximum, he works 20 hours, and earns:
[tex]y(20) = 30(20) + 50 = 650[/tex]
The range of values from one job is between $50 and $650.
9. AC ATis an isosceles triangle with base angles Cand Teach represented by (3 x +11)
degrees, while angle A is represented by (9 x+8) degrees. Find the measure of angle
C.
Answer:
41°
Step-by-step explanation:
A triangle is a shape with three angles and three sides. There are different types of triangles such as equilateral triangle, scalene triangle, isosceles triangle, right angled triangle and so on.
An isosceles triangle is a triangle in which two sides and two angles are equal to each other.
In triangle CAT, ∠C = ∠T (base angles of an isosceles triangle are equal):
∠A + ∠C + ∠T = 180° (sum of angles in a triangle).
Hence substituting gives::
(9x + 8) + (3x + 11) + (3x + 11) = 180
9x + 3x + 3x + 8 + 11 + 11 = 180
15x + 30 = 180
15x = 180 - 30
15x = 150
x = 150 / 15
x = 10°
Hence ∠A = 9x + 8 = 9(10) + 8 = 98°, ∠C = ∠T = 3x + 11 = 3(10) + 11 = 30 + 11 = 41°

Q46. The average of five shirts price is Rs. 750, if the price of three shirts is
Rs. 2400, then what will be the price of other two shirts?
Answer:
Rs 1350
Step-by-step explanation:
An average of 5 shirts is Rs 750
The total amount of the 5 shirts is 750×5
= 3,750
The price of 3 shirts is Rs 2400
Therefore the price of the other two shirts can be calculated as follows
= 3750-2400
= 1350
Hence the price of the other two shirts is Rs 1350

The nth term of 50, 80, 110 is...
Answer:
[tex]a_n=50+(n-1)30[/tex]
Step-by-step explanation:
Given series is,
50,80,110....
First term, a = 50
Common difference, d = 80-50 = 30
We need to find the nth term of the given sequence.
The nth term of an AP is given by :
[tex]a_n=a+(n-1)d[/tex]
Put a = 50 and d = 30 in the above formula
[tex]a_n=50+(n-1)30[/tex]
Hence, the nth term of the sequence is [tex]a_n=50+(n-1)30[/tex].

Cindy, Mary, and Reese will share the cost to rent a vacation home for a week.
Cindy's share represents 40% of the cost.
Mary's share represents 35% of the cost.
Reese's share represents the remainder of the cost.
The cost to rent a vacation home for a week is $850. How much will Reese pay to rent this vacation home for a week?
A) $200.00
B) $297.50
C) $212.50
D) $637.50
If you can plz show your work thank you and this is a 7th grade question have fun
Answer: $212.50
Step-by-step explanation:
Cindy's share = 40% of the cost.
Mary's share = 35% of the cost.
Reese's share = 100% - (40% + 35%) = 100% - 75% = 25%
If the cost to rent a vacation home for a week is $850, the amount that Reese will pay to rent this vacation home for a week will be:
= 25% × $850
= 0.25 × $850.
= $212.50
