Step-by-step explanation:
5x + 7 = 2x - 8 can anyone say how to solve please
Answer:
x = - 5
Step-by-step explanation:
Given
5x + 7 = 2x - 8 ( subtract 2x from both sides )
3x + 7 = - 8 ( subtract 7 from both sides )
3x = - 15 ( divide both sides by 3 )
x = - 5
Omar is painting a 24-square-foot wall. The wall is divided into squares that each measure 14 square foot. How many squares is the wall divided into? Enter your answer in the box.
Complete question :
Omar is painting a 24-square-foot wall. The wall is divided into squares that each measure 1/4 square foot. How many squares is the wall divided into?
Answer:
96
Step-by-step explanation:
Given that:
Total area of wall = 24 ft²
Area of each division =. 1/4 ft²
Number of division = x
The number of divisions * area of each division = total area of wall
x * 1/4ft² = 24ft²
Divide both sides by 1/4 ft²
x = 24ft² ÷ 1/4 ft²
x = 24 * 4 /1
x = 96
Hence, wall is divided into 96 squares

2. Your pet rat Randy is the next contestant on a new game show What a Rat! Where
rats compete in mazes to find food as
fast as possible. Randy is equally
likely to take any path when coming
to an intersection, but you get to
decide which area to place the food.
Given the maze above, in which area
should you place the food to help
Randy win the competition? Show all
of your calculations! Be clear,
complete and justify your answer.
Answer:
Box C
Step-by-step explanation:
Given
See attachment 1 for the maze
Required
The area to place the food in order to help the rat win
To answer this question, we make use of the concept of probability (see attachment 2)
From the starting point to the first joint:
Each of the three ways have the same probability of 1/3
1. If the car passes the way at the top, there are two additional joints.
1.1 Each of the two joints (top and bottom) have the same probability of 1/6 (i.e. divide 1/3 by 2)
1.2 The bottom joint also splits to two (each of these ways have a probability of 1/12; i.e. divide 1.6 by 2)
2. If the car passes the way at the middle, there are two additional joints.
Each of the two joints (top and bottom) have the same probability of 1/6 (i.e. divide 1/3 by 2)
3. If the car passes the way at the bottom, there are three additional joints.
Each of the three joints have the same probability of 1/9 (i.e. divide 1/3 by 9)
Next, is to sum up the probability of each box.
For Box A
[tex]P(A) = \frac{1}{6} + \frac{1}{12} + \frac{1}{9}[/tex]
Take LCM
[tex]P(A) = \frac{6+3+4}{36}[/tex]
[tex]P(A) = \frac{13}{36}[/tex]
[tex]P(A) = 0.361[/tex]
For Box B
[tex]P(B)= \frac{1}{12} + \frac{1}{6}[/tex]
Take LCM
[tex]P(B)= \frac{1+2}{12}[/tex]
[tex]P(B)= \frac{3}{12}[/tex]
[tex]P(B)= 0.250[/tex]
For Box C
[tex]P(C) = \frac{1}{6} + \frac{1}{9} + \frac{1}{9}[/tex]
Take LCM
[tex]P(C) = \frac{3+2+2}{18}[/tex]
[tex]P(C) = \frac{7}{18}[/tex]
[tex]P(C) = 0.389[/tex]
From the calculations above, box C has the highest probability of 0.389 compared to 0.250 (of box B) and 0.361 (of box A)
Hence, the food should be placed in Box C

x + 4y = 16 and 2x + 12y = 48 What is the value of x+y in the solution of the system?
Answer:
x = − 4y + 16
x = − 6y + 24
Step-by-step explanation:
Let's solve for x.
x + 4y = 16
Step 1: Add -4y to both sides.
x + 4y + − 4y = 16 + − 4y
x = − 4y + 16
Answer:
x = − 4y + 16
Let's solve for x.
2x + 12y = 48
Step 1: Add -12y to both sides.
2x + 12y + − 12y = 48 + − 12y/2x= − 12y + 48
Step 2: Divide both sides by 2.
2x/2 = − 12y + 48/2x = − 6y + 24
Answer: x = − 6y + 24

find the x intercept and the y intercept of the graph of the equation 5x+4y=40
Answer:
x intercept is 8, y intercept is 10
Step-by-step explanation:
x intercept is the x value for which the graph crosses the x-axis. Similar for y.
5x + 4y = 40 describes a straight line, so we should have no problem with finding those values
Let's find an x for which y = 0
5x + 4y = 40
substitute y=0
5x = 40
x = 8
Let's find a y for which x = 0
5x + 4y = 40
substitute x=0
4y = 40
y = 10
Determine whether this situation represents independent or dependent events. "Three green jelly bean, five red jelly beans and two orange jelly bean are in a bag. What is the probability of selecting an orange jelly bean, putting it back, and then selecting a green jelly bean?" Question 1 options: Independent Events Dependent Events
Answer:
Independent Events
Step-by-step explanation:
Given
[tex]Green = 3\\ Orange = 2\\ Red = 5[/tex]
Required
Dependent or independent event
The probability of selecting a green jelly remains unchanged before and after selecting the first orange jelly.
Before selecting the orange jelly:
[tex]P(Green) = \frac{Green}{Total}[/tex]
[tex]P(Green) = \frac{3}{10}[/tex]
After selecting the orange jelly:
[tex]P(Green) = \frac{Green}{Total}[/tex]
[tex]P(Green) = \frac{3}{10}[/tex]
Because the probabilities remain unchanged, the selection of a green jelly is independent of the selection of the first orange jelly.

Alexis has a rectangular backyard that is 50 yards by 55 yards. She wants to build a
fence that stretches diagonally from one corner to the opposite corner. About how
many yards of fencing will Alexis need? Round to the nearest tenth.
Given:
Alexis has a rectangular backyard that is 50 yards by 55 yards.
She wants to build a fence that stretches diagonally from one corner to the opposite corner.
To find:
The length of the fencing she needs.
Solution:
We have,
Length = 50 yards
Width = 55 yards
We know that, the diagonal of a rectangle is
[tex]Diagonal=\sqrt{length^2+width^2}[/tex]
[tex]Diagonal=\sqrt{(50)^2+(55)^2}[/tex]
[tex]Diagonal=\sqrt{2500+3025}[/tex]
[tex]Diagonal=\sqrt{5525 }[/tex]
On further simplification, we get
[tex]Diagonal=74.3303437[/tex]
[tex]Diagonal\approx 74.3[/tex]
Therefore, the length of the required fencing is 74.3 yards.

A can of soup is 12 cm tall and has a radius of 4 cm.
What is the volume of soup that the can will hold?
48π cm³
80π cm³
144π cm³
192π cm³
Answer:
192π cm³
Step-by-step explanation:
First, do π(4^2). Then, multiply that times the height. So, 50.24 x 12 = 602.88. But, the question is asking your answer in terms of π. So, do 4^2 x 12. So, 4^2 x 12, gives you the answer: 192. Now change that to make it in terms of π. So, your answer will be: 192π cm³

Solve for q.
3(q − 7) = 27
q =
Answer:
The answer is, q = 16.
Step-by-step explanation:
1) Divide both sides by 3.
[tex]q - 7 = \frac{27}{3} [/tex]
2) Simplify 27/3 to 9.
[tex]q - 7 = 9[/tex]
3) Add 7 to both sides.
[tex]q = 9 + 7[/tex]
4) Simplify 9 + 7 to 16.
[tex]q = 16[/tex]
Therefor, the answer is q = 16.
Answer:
q=16
Step-by-step explanation:
To solve this problem, you'll want to start by distributing the 3 to both q and -7, which will give you 3q-21=27. Then, you should add 21 to both sides, which will get the variable alone on one side of the equation. After that step, your equation should be 3q=48. Lastly, divide both sides by 3, which will give you the answer q=16!
