A school is looking to cater an event by having a food truck. Food truck A will charge $1.50 for each item sold and a fee of $50 to come to the school. Truck B will charge $2.75 per item but will not charge a fee to come to the school. How many items must the school purchase to have the cost of these two trucks be the same? Enter in your numerical answer.
Answer:
40 items
Step-by-step explanation:
I used the equation 1.5x+50=2.75x to find the answer. If the school were to buy 40 items from either truck, they would both amount to 110.

evaluate. (5.2 + 3) × (6.4 - 1.4)
2(-2×-8)+4×=2(1+3×) someone pls help
Answer:
x=-3
Step-by-step explanation:
2(-2x-8) + 4x = 2(1+3x)
Distribute:
-4x-16+4x=2+6x
Simplify Like-Terms:
-16=2+6x
Subtract 2 from both sides:
-18=6x
Divide both sides by 6:
x=-3

Step-by-step explanation:
a.) solve 7x+4=18 because EC bisects making FEC = CEG
b.) solve 12y+18=90 because AED is 90 degrees
Whoever answer this question with explanation gets marked the brainiest
Step-by-step explanation:
Classroom A has n students.
Since Classroom B has 4 less students, they have (n - 4) students.
Also Classroom C has double the students in B, so they have 2(n - 4) students.
We have A + B + C = 40.
=> n + (n - 4) + 2(n - 4) = 40
=> n + n - 4 + 2n - 8 = 40
=> 4n - 12 = 40
=> 4n = 52, n = 13.
Hence there are 13 students in Classroom A.

Step by step explanation
Answer: x = 4 and y = -3
Step-by-step explanation:
2x + 4y = -4
2x = -4 - 4y
x = -2 - 2y
Now that we have solved the first equation for x, we plug (-2 - 2y) into the other equation in place of x and then solve for y.
3(-2 -2y) + 5y = -3
-6 - 6y + 5y = -3
-y = 3
y = -3
Now that we know y, we plug it into the original equation and solve for x.
2x + 4(-3) = -4
2x + -12 = -4
2x = 8
x = 4
You can check the answer by plugging both x and y into either of the original equations.
which linear inequality is represented by the graph? O y<2/3x+3 (A)
O y>3/2x+3 (B)
O y>2/3x+3 (C)
O y<3/2x+3 (D)
Answer:
C y>2/3x+3
Step-by-step explanation:
Use y=mx+b format. The B is the y-intercept. From the y-intercept (3), go up two then to the right 3. That gives you the slope, or mx which is 2/3. The area shaded is above so it would be the greater than symbol.
A truck is carrying cranberry juice, grape juice, and pineapple juice bottles in a ratio of
7 : 2 : 3. If there are 40 grape juice bottles, then how many juice bottles in total are there?
Answer:
140
Step-by-step explanation:
7- Cranberry
2:Grape = 40 so 40/2 = 1
3:Pineapple
1= 20 juices
7+2+3 is 12
20 x 12 is 140
23x+50x-79x=??
have a great day
Answer:
-6x
Step-by-step explanation:
23x+50x-79x
We take out x from the terms and group them up.
We therefore get (23+50-79)x after taking out x, and grouping the coefficients together.
Calculating 23+50-79 gets us -6, which is the coefficient of the final answer.
So the answer would be -6x.
Answer:

A number, x, is 4 times another number, y. The difference
between the two numbers is 18. What is the value of the
larger number?
Answer:
The value of the larger number is
[tex]x=24[/tex]
Step-by-step explanation:
A number, x, is 4 times another number, y.
[tex]x=4y[/tex] --------- (1)
The difference between the two numbers is 18.
[tex]x-y=18[/tex] -------(2)
Re-arranging equation (2) yields
[tex]-y=18-x\\y=x-18[/tex]------------- (3)
Substitute y=x-18 in equation (1)
[tex]x=4 (x-18)[/tex]
[tex]x=4x-72\\x-4x=-72[/tex]
[tex]-3x=-72\\x=\frac{72}{3}\\x=24[/tex]
Substitute x=24 in equation (3)
[tex]y=24-18\\y=6[/tex]

Answer:
C.) 32
Step-by-step explanation:
2^5 = 32
1.2^a x 2^5 =2^0
a=?
Answer:
One thing that is unclear here is whether the "1." at the start is part of the number "1.2" or if it is an enumeration of the question, and the base raised to the exponent is in fact 2.
The rest of the equation seems to indicate the latter, so we'll solve both:
If 1.2ᵃ ₓ 2⁵ = 2⁰, then a is approximately equal to -19.009.
If as I'm guessing is the correct question, 2ᵃ ₓ 2⁵ = 2⁰, then a is equal to -5.
Step-by-step explanation:
Interpretation #1:
[tex]1.2^a \times 2^5 = 2^0\\1.2^a \times 32 = 1\\1.2^a = \frac{1}{32}\\log_{1.2} \frac{1}{32} = a\\a \approx -19.009[/tex]
Interpretation #2:
Here the question is much simpler, as we need only add the exponents when adding and dividing:
[tex]2^a \times 2^5 = 2^0\\2^a = 2^0 \div2^5\\2^a = 2^{-5}\\a = -5[/tex]

Need help it’s really hard
Given:
[tex]OA=3[/tex] units
[tex]OA'=9[/tex] units
To find:
The scale factor of the dilation.
Solution:
From the given figure it is clear that the center of dilation is point O. Point A' is the image of point A. So,
[tex]\text{Scale factor}=\dfrac{OA'}{OA}[/tex]
Putting the given values, we get
[tex]\text{Scale factor}=\dfrac{9}{3}[/tex]
[tex]\text{Scale factor}=3[/tex]
Therefore, the scale factor of the dilation is 3.
