Answer:
He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins
Step-by-step explanation:
System of Equations
Let's call
x = pounds of trail mix 5% raisins
y = pounds of trail mix 20% raisins
The distributor wants to make 1,000 pounds of trail mix, thus:
x + y = 1,000 [1]
The mix must be 8% raisings as a combination of x and y, thus:
5x + 20y = 8*1,000 = 8,000
Dividing by 5:
x + 4y = 1,600 [2]
Subtracting [2] and [1]:
4y - y = 1,600 - 1,000
Operating:
3y = 600
y = 200
From [1]
x = 1,000 - y = 1,000 - 200
x = 800
He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins
Answer:
5% raisin mix: 800 lbs
20% raisin mix: 200 lbs
Step-by-step explanation:
Let number of 5% be x; and number of 20% be a.
x + y = 1000
5% · x + 20% · y = 8% of 1000 pounds
0.05x + 0.2y = 80
x = 1000 - y
0.05(1000 - y) + 0.2y = 80
50 - 0.05y + 0.2y = 80
0.15y = 30
y = 200
x = 1000 - y
x = 1000 - 200
x = 800

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

2(x + 1 ) - 3(x + 5) ≥ 0
plss help
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

What’s the slope of the line ?
Answer:
y= 2x-2
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
Find two lattice points
I chose (-2, 0) and (0, -2)
Since you are using a graph, you don't need an equation.
Starting from (-2, 0), you go down -2 points and 2 across to get to the second point.
-2/2 = -1
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.

Justin calculates the perimeter of a rectangle with a length of 2x-3 and width
of X+4. He tells his teacher the answer is 3x-1. Is he correct or incorrect and why?
Answer:
No
Step-by-step explanation:
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
Step-by-step explanation:
The equation for perimeter is 2L+ 2W=P
so 2 (2x-3) + 2 (x+4) = 6x+2

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

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
