The math department needs to buy new textbooks and laptops for the computer science classroom. The textbooks cost $116.00 each, and the laptops cost $439.00 each. If the math department has $6,500 to spend and purchases 30 textbooks, how many laptops can they buy
Answer:
6 laptops
Step-by-step explanation:
First, find the amount spent on the textbooks:
30(116)
= 3480
Subtract this from the total amount they have to spend:
6500 - 3480
= 3020
Divide this amount by 439 to find how many laptops they can buy:
3020/439
= 6.8
Round down to 6 since you can only have full laptops:
= 6
So, they can buy 6 laptops
Andy spent $46.95 at the grocery store. The cashier gave him $2.97 in change from a $50 bill. How much change should the cashier have given Andy? A) $2.95 B) $3.00 09 $3.05 D $3.15
The cashier should have given Andy back $3.05
so the answer is C-$3.05
The cashier should have given Andy back $3.05 if Andy spent $46.95 at the grocery store option (c) $3.05 is correct.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
It is given that:
Andy spent $46.95 at the grocery store. The cashier gave him $2.97 in change from a $50 bill.
Let x be the change the cashier should have given Andy.
x + 46.95 = 50
x = 50 - 46.95
x = $3.05
Thus, the cashier should have given Andy back $3.05 if Andy spent $46.95 at the grocery store option (c) $3.05 is correct.

Find the slope of the line that passes through (1, 13) and (10, 6).
Find an equation for the line below.
Help me please :(
Answer:
y=3/2x+5/2
Step-by-step explanation:
I used the Y2-Y1/X2-X1
In this equation you can see that there are 2 points (-5,-5) and (1,4)
If you substitute, you will get
4+5/1+5
9/6 and if you simplify this, you will get 3/2
Now that we have the slope, we just have to use y=mx+b
(I'm using the point (1,4)) 4=3/2(1)+b
4=3/2+b
5/2=b

Answer:
Inequality form x less than or equal to -13
Step-by-step explanation
Answer:
x ≤ -13
Step-by-step explanation:
2(x + 1) - 3(x + 5) ≥ 0
Distribute the 2
(2 × x) + (2 × 1)
2x + 2 - 3(x + 5) ≥ 0
Distribute the -3
(-3 × x) + (-3 × 5)
2x + 2 - 3x + (-15) ≥ 0
2x + 2 - 3x - 15 ≥ 0
Combine like terms
2x - 3x + 2 - 15 ≥ 0
-x + (-13) ≥ 0
-x - 13 ≥ 0
+13 +13
-x ≥ 13
Divide both sides by -1 and flip the sign
x ≤ -13

3(2y - 0.3) = 19.4 - y
Answer:
y=2.9
Step-by-step explanation:
3(2y - 0.3) = 19.4 - y
6y-0.9=19.4
6y+y-0.9=19.4
6y+y=19.4+0.9
7y=19.4+0.9
7y=20.3
7y/7=20.3/7 (divid each one by seven. that's what /7 means)
y=2.9

of X+4. He tells his teacher the answer is 3x-1. Is he correct or incorrect and why?
Answer:
No

No, because the perimeter of a rectangle is 2(x+y). Justin added the sides. Then he should have multiplied by 2 but he didn't so Justin is incorrect.
Hope this helps plz mark brainliest :D
Answer:
No, his answer should have been 6x+2

What is an equation of the line that passes through the points (4,−1) and (8, 5)? Put your answer in fully reduced form.
HELP PLS
Answer:
y=2/3x-7
Step-by-step explanation:
The slope intercept formula is
y=mx+b
(m) is the slope (rate of change)
(b) is the y intercept (where the line crosses the y axis [vertical])
We need to find the slope and the y intercept. First we will find the slope.
The formula for slope is y1-y2/x1-x2
In and ordered pair the first value is the (x) and the second is the (y).
(x, y)
We take the (y) of one of the given points and subtract the (y) of the second given point, then divide it by the (x) of one of the given points and the (x) of the other given point.
5-(-1)/8-4
Simplify.
5-(-1) =5+1= 6
8-4=4
6/4 Simplify
3/2 is our slope.
Now we apply out new slope into our y=mx+b
y=3/2x+b
Now we need to find the (b) which is the y intercept.
To do this we need to use one of our given points, you can choose either but for this I'll use (4, -1).
In this ordered pair 4 is the (x) and -1 is the (y)
So replace (y) with -1 and (x) with 4
-1=3/2(4)+b
Now solve as usual.
-1=6+b
subtract 6 from each side
-7=b
b=-7
Put our (m) and (b) into our formula.
y=2/3x-7 is our equation.

C. Infinite
The ratio of the coefficient is the same so it will be the infinite solution of a given system of the equation so option (C) will be correct.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
A linear equation could contain more than one variable. When the maximum power of the variable is constantly uni, an equation is said to be linear.
Given the set of equation
4x - 2y = 12
20x - 10y = 160
The ratio of x coefficient = 4/20 = 1/5
The ratio of y coefficient = -2/-10 = 1/5
The ratio of the constant term = 12/160 = 1/5
Since all ratios are the same so there will be an infinite number of solutions.
The question was incomplete, but the complete question is given below.
