Answer:
a = 3 - (7/4)b
Step-by-step explanation:
Start by performing the indicated multiplication:
2a+3b=12-2(2b+a) => 2a+3b=12 - 4b - 2a
Next, combine like terms: 4a + 7b = 12
Isolate 4a by subtracting 7b from both sides:
4a = 12 - 7b
Finally, divide both sides by 4:
a = 3 - (7/4)b

Step-by-step explanation:
Abbie opened a no-interest bank account with $20, and she deposits $14.50 every week. Carlos opened a no-interest bank account with $28, and he deposits $12.50 every week. Carlos and Abbie do not make any withdrawals from their accounts. The equation below can be used to find w, the number of weeks it will take for the balances in their accounts to be the same. 20 + 14.50w = 28 + 12.50w What value of w makes this equation true?
Answer:
4 weeks
Step-by-step explanation:
14.50 (4) + 20= 78
12.50 (4) + 28= 78
Carol's car average is 17.1 miles per gallon in City driving and 24.7 miles per gallon in highway driving if she drove a total of 513.0 miles on 26 gallons of gas how many of the gallons were used for City driving
Answer:
the volume of the gas used for city driving is 17 gallons
Step-by-step explanation:
Given;
average speed for city driving, v₁ = 17.1 miles per gallon
average speed for highway driving, v₂ = 24.7 miles per gallon
total distance traveled, d = 513 miles
total gallon of gas used, t = 26 gallons
Let the volume of gas used for city driving = x
Also, let the volume used for highway driving = y
x + y = 26 -------- (1)
17.1x + 24.7y = 513 ------------(2)
From equation (1); y = 26 - x
Substitute the value of y in equation (2)
17.1x + 24.7(26-x) = 513
17.1x + 642.2 - 24.7x = 513
17.1x - 24.7x = 513 - 642.2
-7.6x = -129.2
x = 129.2/7.6
x = 17 gallons
Therefore, the volume of the gas used for city driving is 17 gallons

There are 500 students in a school. Sara asked 100 of the students what their favorite lunch is. Out of the students surveyed 45 said pizza, 15 said burritos, 30 said hamburgers, and 10 said hot dogs. Based upon the results, how many students out of the whole school should want the items listed? (Round to the nearest whole number.) Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50 Pizza: 22500 Burritos: 7500 Hamburgers: 15000 Hot Dogs: 5000 Pizza: 125 Burritos: 125 Hamburgers: 125 Hot Dogs: 125 Pizza: 45 Burritos: 15 Hamburgers: 30 Hot Dogs: 10
Answer: Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50
Step-by-step explanation:
Since Sara asked 100 of the students for their favorite lunch but there are 500 students in a school, this means that the items listed will have to be multiplied by 5 (500/100) in order to get the number of students in the whole school that'll need the items listed. This will therefore be:
Pizza = 45 × 5 = 225
Burritos = 15 × 5 = 75
Hamburgers = 30 × 5 = 150
Hot dogs = 10 × 5 = 50
The correct option is A:
Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50

x-2y=4 in slope intercept form
Answer:
y = 1/2x - 2
Step-by-step explanation:
Slope intercept form:
y = mx + b
x - 2y = 4
-2y = -x + 4
2y = x - 4
y = 1/2x - 2

A rectangle has vertices A(0, 0), B(0, 9), C(4, 9), and D(4, 0). What is the perimeter of the rectangle
Answer:
26 units
Step-by-step explanation:
A rectangle has vertices A(0, 0), B(0, 9), C(4, 9), and D(4, 0). What is the perimeter of the rectangle
We have to find the length of the sides of the rectangle using the formula below
= √(x2 - x1)² + (y2 - y1)² when given vertices (x1, y1) and (x2, y2)
For side AB
A(0, 0), B(0, 9)
= √(0 - 0)² + (9 - 0)²
= √0 + 81
= √81
= 9 units
For side BC
B(0, 9), C(4, 9)
= √(4 - 0)² + (9 - 9)²
= √4² + 0²
= √16
= 4 units
For side CD
C(4, 9), and D(4, 0)
= √(4 - 4)² + (9 - 0)²
= √0² + 9²
= √81
= 9 units
For side AD
A(0, 0), D(4, 0).
= √(4 - 0)² + (0 - 0)²
= √4² + 0
= √16
= 4 units
We can see than
AB = CD = 9 units
BC = AD = 4 units
The perimeter of a rectangle = 2(L + W)
From the above calculation
Length = 4 units
Width = 9 units
Perimeter = 2(4 + 9) units
= 2 × 13 units
= 26 units

WRITE THE RATIO: A cookie recipe calls for 1 cup of flour to make 24 cookies. Create a proportion to show how many cups of flour are needed to make 36 cookies
Answer:
1&(1/2) or 1.5 or 3/2 cups flour needed for 36 cookies
Step-by-step explanation:
Flour : Cookie ratio (Flour needed to make particular cookie) = 1 : 24
1 cup flour make 24 cookies, so 1/2 cup floor make 12 (half) cookies.
So, 1&(1/2) or 1.5 or 3/2 cups would make 24 + 12, ie = 36 cookies
AlternativelyMultiplying numerator & denominator of fractional ratio 1 : 24 with 1.5 each
(1 x 1.5) : (24 x 1.5)
It implies 1.5 : 36 flour cookie ratio
