Solve using elimination ?
Answer:
for the first one its x=30
for the second one its x=6
Step-by-step explanation:
its x=30 because at the end if you do the problem yourself, you would have to multiply 5×6 which is 30.
im not sure why its x=6 on that one i might be wrong but i did it but im also confused on it but i tried so yeah maybe it is.
Jacque needs to buy some pizzas for a party at her office. She’s ordering from a restaurant that charges a $7.50 delivery fee and $14 per pizza. She wants to buy as many pizzas as she can, and she also needs to keep the delivery fee plus the cost of the pizzas under $60.
Each pizza is cut into 8 slices, and she wonders how many total slices she can afford.
Q: What is the largest number of slices that Jacque can afford?
Lets answer the information by making it look like a budget subtraction:
60 = Total
1. Remove the delivery cost, so you can leave the rest of the budget for your pizzas.
60 - 7.50 = 52.50
2. Now, subtract the cost of pizzas multiple times until you reach it to where you dont have enough for another pizza.
52.50 - 14 = 38.50 Pizza 1
38.50 - 14 = 24.50 Pizza 2
24.50 - 14 = 10.50 Pizza 3
Now, theres not enough to buy another.
So, we know that Jacque can only afford 3 pizzas, but she need to calculate the number of slices.
3. Multiply the number of slices by the number of pizzas.
8 x 3 = 24
So, the largest number is 24 slices.
Answer:
60

Help With the question on the image.
The ratio of the perimeters of 2 similar shapes is the sidelength of 1 shape to the matching sidelength. That means the ratios of the perimeters are 10:6 = 5:3
The ratio of areas = ratio of perimeters ^2 --> 25:9
Ratios of areas = ratios of perimeters ^2
Find the 10th term of the sequence defined by the given rule. Assume that the domain of each function is the set of whole numbers greater than 0.
f(1) = 8, f(n) = f(n − 1) + 15
The 10th term is
Answer:
[tex]87.[/tex]
Step-by-step explanation:
[tex]f(1) = 8, f(n) = f(n − 1) + 15 \\ The \: 10th \: term \: is \: \\ 8(10 − 1) + 15 = 72 + 15 = 87.[/tex]

NEED HELP!! ASAP!! 50 POINTS!!
Write an equation of the line that passes through the given point an satisfies the given condition.
(-3,-5); parallel to y = -4x + 1
-6 = -1/2(9) + B
-6 = 4.5 + B
-6--4.5 = B
-1.5 = B
B= -1.5
y=-1/2x - 1.5
y=-1/2(9) - 1.5
y= -4.5-1.5
y=-6
A company sells widgets. The amount of profit, y, made by the company, is related to
the selling price of each widget, x, by the given equation. Using this equation, find out
what price the widgets should be sold for, to the nearest cent, for the company to
make the maximum profit.
y=-8x² + 539x – 3710
8^2 gives you 64. 64x + 539x=603.
Step-by-step explanation:
Your answer would be y=603x-3710
if x and y vary directly, and x=3/4 and y =15 which of following represents this situation?
a x=11.25y
b y=11.25x
c x=20y
d y=20x
Answer:
A
Step-by-step explanation:
Because your not studying
Answer:
D
Step-by-step explanation:
simple plug and chug.
Understand that variables are already defined, x=3/4, y=15 meaning that if we plug one of the variables into an equation, we should obtain the other variable's number.
y=20x will result in y=15 when x=3/4 and vice versa.

Mr. Carter is building a circular fire pit in his backyard. The diameter of the fire pit is 6 feet and he will fill the interior with gravel covering 5/6 of the area. How much gravel will he need?
A. 23.55 sq. ft.
B. 28.26 sq. ft.
C. 94.2 sq. ft.
D. 113.04 sq. ft.
Answer:
23.55
Step-by-step explanation:
To calculate the area I did the following equation
area = 3.14 (r) (r)
area = 3.14 (3) (3)
area = 28.26
The area is 28.26 but the question is asking how much gravel would be needed to fill 5/6 of the area.
The equation for 5/6 out of 28.26 is
28.26 (5/6) = 23.55
So the final answer is (a.) 23.55 sq. ft.

Mrs. Potter was going through her Halloween candy to see which kind she would bring to school. She sorted using decimal values. .17 of her 100 pieces were black licorice. .42 were m&m's. .12 were skittles. .09 were smarties. .14 were lollipops and .06 were gum drops. Mrs. Potter decided to bring the black licorice and the gum drops to school. What percent of her candy did she bring to school?
Answer:
23%
Step-by-step explanation:
She sorted using decimal values.
We convert the decimals to percent
.17 of her 100 pieces were black licorice.
.17 = 0.17 × 100 = 17%
.42 were m&m = 0.42 × 100 = 42%
.12 were skittles. = 0.12 × 100= 12%
.09 were smarties = 0.09 × 100= 9%
.14 were lollipops = 0.14 × 100 = 14 %
.06 were gum drops. = 0.06 × 100= 6 %
Mrs. Potter decided to bring the black licorice and the gum drops to school. What percent of her candy did she bring to school?
Licorice = 17%
Gum drops = 6%
The percent of her candy that she brought to school = 17% + 6%
= 23%
The percent of her candy that she brought to school is 23%
