Hi please help i am stuck with this question i will mark for brainliest
And 100. Point
Answer: 9
Step-by-step explanation:
First solve the system (using elimination):
x-y=7...(1)
3x+2y=26...(2)
Multiply equation 1 by -3
-3x+3y=-21
+ 3x+2y=26
-----------------
5y=5
y=1
Substitute y=1 into equation 1
x-y=7
x-(1)=7
x=8
Let a=8 (x=a) and y=1 (y=b)
a + b
= (8) + (1)
= 9
Information provided with us :
x is assumed as a y is assumed as bWhat we have to calculate :
Value of a + b ?Performing Calculations :
Here we have been given with two equations,
x - y = 7 (First equation) 3x + 2y = 26 (Second equation)From the first equation we would be getting a value of x and that value of x we would substitute in the second equation.
⇒ x - y = 7
⇒ x = 7 + y
Now, substituting it in the second equation :
⇒ 3x + 2y = 26
⇒ 3 (7 + y) + 2y = 26
⇒ 3 × (7 + y) + 2y = 26
⇒ 21 + 3y + 2y = 26
⇒ 21 + 5y = 26
⇒ 5y = 26 - 21
⇒ 5y = 5
⇒ y = 5 / 5
⇒ y = 1
★ Therefore, value of y is 1.
Now, substituting this value of y as 1 in the first equation.
⇒ x - y = 7
⇒ x - 1 = 7
⇒ x = 7 + 1
⇒ x = 8
★ Therefore, value of x is 8.
Value of a + b :-
⇒ x = a = 8
⇒ y = b = 1
Now,
⇒ a + b
⇒ 8 + 1
⇒ 9
Henceforth, value of a + b is 9.

Simplify 12A + 2 + A - 1.
13 A + 1
14 A - 1
13 A - 1
Answer:
13A + 1
Step-by-step explanation:
Combine like terms. Like terms are terms that have the same amount of the same variable:
Set the expression:
12A + A + 2 - 1
(12A + A) + (2 - 1)
13A + 1
13A + 1 is your answer.
~
Hey there!
12a + 2 + a - 1
COMBINE the LIKE TERMS
= (12a + 1a) + (2 - 1)
= 12a + 1a + 2 - 1
= 13a + 1
Therefore, your answer is: 13a + 1
Good luck on your assignment & enjoy your day!

Two punches are made from steel bar stock 9 7/16 inches long. If one punch is 4 1/64 inches long and the other is 4 3/32 inches long, how many inches of stock are wasted?
a. 1 1/16 inches
b. 1 5/16 inches
c. 1 15/64 inches
d. 1 21/64 inches
Answer:
d. 1 21/64 inches
Step-by-step explanation:
Add the lengths of the two punches.
4 1/64 + 4 3/32 = 4 1/64 + 4 6/64 = 8 7/64
Subtract the sum from the length of the bar stock.
9 7/16 - 8 7/64 = 9 28/64 - 8 7/64 = 1 21/64
Answer: d. 1 21/64 inches
The 1 15/64 inches of stock are wasted (option c).
To find out how much stock is wasted, we need to subtract the sum of the lengths of the two punches from the original length of the steel bar.
Original length of the steel bar = 9 7/16 inches
Length of the first punch = 4 1/64 inches = 4 + 1/64 inches
Length of the second punch = 4 3/32 inches = 4 + 3/32 inches
Total length of the two punches = (4 + 1/64) + (4 + 3/32) inches
Now, add the lengths of the two punches:
Total length of punches = 8 + 1/64 + 3/32 inches
Convert the fractions to a common denominator (64):
Total length of punches = 8 + 1/64 + 6/64 inches
Total length of punches = 8 + 7/64 inches
Now, subtract the total length of punches from the original length of the steel bar:
Wasted stock = 9 7/16 - (8 + 7/64) inches
Convert 9 7/16 to an improper fraction:
Original length of the steel bar = 9 * 16/16 + 7/16 = 151/16
Now, subtract the total length of punches:
Wasted stock = 151/16 - (8 * 16/16 + 7/64)
Wasted stock = 151/16 - (128/16 + 7/64)
Wasted stock = 151/16 - 130/16 - 7/64
Wasted stock = 21/16 - 7/64
Wasted stock = (21 * 4)/(16 * 4) - 7/64
Wasted stock = 84/64 - 7/64
Wasted stock = 77/64 inches
Now, let's simplify 77/64:
77/64 = 64/64 + 13/64 = 1 + 15/64 inches

Answer:
Step-by-step explanation:
The first step is to figure out what the % is on the right.
The total is 100%
The left side is 60%
The right side is 100% - 60% = 40%
Now the 40% represents 28 students
The total number of students is 100%
40%/100% = 28/x Cross multiply
40% x = 28 * 100% Divide both sides by 40%
x = 28 * 100 / 40
x = 70
So the total number of students is 70
60% of them are on the left. 60/100 * 70 = 42
There are 42 students on the left.
