What are the possible steps involved in solving the equation shown? Select three options.
3.5 + 1.2(6.3 - 7x) = 9.38
O Add 3.5 and 1.2.
O Distribute 1.2 to 6.3 and -7x
O Combine 6.3 and -7x
O Combine 3.5 and 7.56.
D Subtract 11.06 from both sides.
Answer:
Distribute 1.2 to 6.3 and -7x
Combine 3.5 and 7.56
suhtract 11.06 from both sides

Brian sold fruit at his stand. Apples cost $0.40 and pears cost $0.50 each. In an afternoon he
sold 52 pieces of fruit and made $24. How many of each did he sell?
Answer:
20 apples, 32 pears
Step-by-step explanation:
Using a for number of apples and p for number of pears, you get a+p=52 (amount) and 0.4a+0.5p=24 (cost).
One way of solving simultaneous equations is using like terms and adding/subtracting them to remove a variable. There aren't any like terms here, but we can create some by multiplying terms.
Multiplying the second equation by 2 gives 0.8a+p=48, so that makes a like term.
Since the symbols are the same in front of the like term, we subtract the second term from the first one. This gives 0.2a=4.
Dividing by 0.2 gives a=20.
We can sub this into either equation to get the value of p.
a+p=52, so 20+p=52, meaning p=32.

A rectangle has length (x+3)cm and width (x-2).Given that it's area is 50cm2,find the dimensions of the rectangle
Answer:
length- 10cm, width- 5cm
Step-by-step explanation:
You want to convert this into an algebraic equation.
Since a=lw, in this case, 50=lw. Subbing (x+3) for l and (x-2) for w, we get the equation (x+3)(x-2)=50.
Using FOIL, we can expand the brackets to make x²-2x+3x-6=50 and collect like terms to x²+x-6=50.
We want all the numbers on one side (to use the null factor law), so we subtract 50 from both sides. This gives x²+x-56=0.
From there, we factorise it, which becomes (x-7)(x+8)=0. (I used the cross method for this)
With the null factor law, one of the brackets must be equal to 0, meaning x-7=0 or x+8=0. This gives x as either 7 or -8.
With measurement, units must be positive, meaning it has to be 7. We can sub this for x in the 2 equations (length and width) to get the answers.
Length=x+3 becomes 7+3, which is 10cm.
Width=x-2 becomes 7-2, which is 5cm.
**This content involves writing, expanding, and factorising quadratic equations, and the null factor law which you may wish to revise. I'm always happy to help!

Identify the type of correlation that is present in the scatter plot.
Answer:
No correlation
Step-by-step explanation:
There is not a positive line of dots
There is not a negative line of dots
so that means there is no correlation
Answer: B) no correlation
Explanation: The points appear to be randomly scattered about. They are not close to or on the same straight line, so we don't have any linear correlation (or that linear correlation is very weak).

what are the roots of the quadratic equation below? 3x^2+15x-5=0
Answer:
X1 = [tex]\frac{=15+\sqrt{285} }{6}[/tex] and X2 = [tex]\frac{-15-\sqrt{285} }{6}[/tex]Step-by-step explanation:
To find the roots of a quadratic equation, you need to solve the quadratic equation by using the quadratic formula.
OR
You can use the (Equation/Function) mode on the calculator.
[tex]\frac{-b+-\sqrt{b^{2} -4ac } }{2a} x \neq 0[/tex]
For this equation,
a = 3
b = 15
c = -5
X1 = [tex]\frac{-15+\sqrt{15^{2} -4(3)(-5) } }{2(3)} x \neq 0[/tex]
X2 = [tex]\frac{-15-\sqrt{15^{2} -4(3)(-5) } }{2(3)} x \neq 0[/tex]
Solving this on the calculator and you should get
X1 = [tex]\frac{=15+\sqrt{285} }{6}[/tex] X2 = [tex]\frac{=15-\sqrt{285} }{6}[/tex]
a, b, c = constants, where a ≠ 0
x = the unknown

A pizza parlor uses square prisms for their pizza boxes. Due to the crust rising, the height of their boxes is always 2 inches. Additionally, the volume of the pizza box must be 450 cubic inches to fit their standard-sized pizza. A worker determined that the equation 2x2 = 450 could be used to find the side length, x, of the box needed to reach that volume.

which statements describe the procedure Dave used in this step and identifies the property that justifies the procedure?
9514 1404 393
Answer:
A
Step-by-step explanation:
The second equation differs from the first in that -9 is a term added to both sides of the equation. The addition property of equality tells you that doing this will not change the value of the variable.
_____
The reason (not justification) for doing this is that the sum of 9 and its additive inverse is 0, the additive identity element. This means the equation can be simplified to 3x = 12, which is the point of making that step (subtracting 9).

You and your friend are selling magazine subscriptions for a fundraiser. After w weeks, you have sold (2w+9) subscriptions and your friend has sold (6w+3) subscriptions.
Answer:
3/2 weeks
Step-by-step explanation:
The question: find the number of weeks you and your friend sells equal number of magazine
You = 2w + 9
Your friend = 6w + 3
Equate both equations
2w + 9 = 6w + 3
Collect like terms
2w - 6w = 3 - 9
- 4w = - 6
w = -6/-4
w = 3/2 weeks

9
X nickels
13
X dimes
9514 1404 393
Answer:
4 nickels12 dimesStep-by-step explanation:
Let d represent the number of dimes. Then 16-d is the number of nickels, and the total value is ...
0.10d +0.05(16 -d) = 1.40
0.05d + 0.80 = 1.40 . . . . . . . eliminate parentheses
0.05d = 0.60 . . . . . . . . subtract 0.80
d = 12 . . . . . . . .dimes
(16 -d) = 4 . . . . nickels
Diane has 12 dimes and 4 nickels.
Jada walks up to a tank of water that can hold up to 10 gallons how many more minutes will it take for the tank to drain completely explain or show your reason
Answer:
7.5 minutes
Step-by-step explanation:
Given
See attachment for complete question
Let
[tex]t \to time[/tex]
[tex]y \to capacity[/tex]
From the question, we have the following points
[tex](t_1,y_1) = (0,7)[/tex] --- When he first sees it
[tex](t_2,y_2) = (3,5)[/tex] --- 3 minutes later
First, we calculate the rate (m)
[tex]m = \frac{y_2 -y_1}{t_2 -t_1}[/tex]
[tex]m = \frac{5 -7}{3 -0}[/tex]
[tex]m = -\frac{2}{3}[/tex]
The discharge rate is 2/3 gallons per minute
To calculate the additional minute, we simply consider the capacity of the tank at the later time. i.e. 5 gallons
To calculate time (t), we have:
[tex]Rate * Time = Capacity[/tex]
[tex]\frac{2}{3} * t = 5[/tex]
Solve for t
[tex]t = 5 *\frac{3}{2}[/tex]
[tex]t = \frac{15}{2}[/tex]
[tex]t = 7.5[/tex]

Given:
A figure of a rectangular prism with length l, width w and height h.
To find:
The surface area of the rectangular prism.
Solution:
The product of twice of the length l and the width w is:
[tex]2\times l\times w=2lw[/tex] ...(i)
The product of twice of the length l and the height is:
[tex]2\times l\times h=2lh[/tex] ...(ii)
The product of twice of the width w and the height h is:
[tex]2\times w\times h=2wh[/tex] ...(iii)
The surface area of the prism is the sum of (i), (ii) and (iii). So, the expression for the surface area is:
[tex]A=2lw+2lh+2wh[/tex]
[tex]A=2(lw+lh+wh)[/tex]
Therefore, the required expression is [tex]2(lw+lh+wh)[/tex].
