a photo collage consists of seven equal sized square photo arranged in a row to form a rectangle if the total area of the college is 567 square inches what is the length of the collage
Answer:
Step-by-step explanation:
I have attached a written explanation to help :).
Let's say each side of the square =[tex]x[/tex]
If we put 7 squares in a row to make the rectangle,
length of the rectangle = [tex]7x[/tex]
Area of a rectangle = length multiplied by width
Area of rectangle = [tex]7x[/tex] multiplied by [tex]x[/tex] = [tex]7x^2[/tex]
We are also told that the total area = 567
So [tex]7x^2 = 567[/tex]
Now solve for [tex]x[/tex].
Divide both sides by 7.
[tex]\frac{7x^2}{7} = \frac{567}{7}[/tex]
[tex]x^2 = 81[/tex]
Then square root both sides to find [tex]x[/tex]
[tex]x = \sqrt{81}[/tex] = 9
Finally, the question asks to find the length of the collage which we said was [tex]7x[/tex] and we know [tex]x = 9[/tex]
Length of collage = [tex]7x = 7[/tex] multiplied by [tex]9[/tex] = ?

Clare made an error when solving – 4x + 3 < 23.
Describe the error that she made.
- 4x + 3 =23
- 4x < 20
Step-by-step explanation:
-4x + 3 < 23
-4x < 20
x > -5
hmm,I don't think we need to put equal sign instead of (<) , for when we started calculating.
we can just keep the question as it is and calculate.
The error Clare made in solving the inequality -4x + 3 < 23 is in the last step. The correct solution should be x > -5, not x < -5.
When dividing or multiplying both sides of an inequality by a negative number, the direction of the inequality symbol should be flipped. In this case, since we are dividing by -4, which is negative, the inequality should be reversed.
The correct steps to solve the inequality are as follows:
-4x + 3 < 23
Subtract 3 from both sides:
-4x < 20
Divide both sides by -4 (remembering to flip the inequality symbol):
x > -5
Therefore, the correct solution is x > -5, indicating that x is greater than -5, not less than -5 as Clare mistakenly wrote.

Write an equation of the line that passes through the points (-3,5) and (2,15)
Answer:
y = 2x + 11
Step-by-step explanation:
Find Slope
(15 - 5) / (2 - (-3)) = 10/5 = 2
Insert One Ordered Pair and Slope into Point Slope Formula
(y - y1) = m(x - x1)
(2,15) and slope = 2
(y - 15)= 2(x-2)
Evaluate
y -15= 2x-4 → y = 2x + 11
Answer =
y = 2x + 11

Jesse is saving the money he earns in his piggybank. He had already earned
$60 from previous work. He charges $15 to mow one lawn. After mowing 4
lawns, how much total money will he have in his piggybank?
Answer:
Jesse will have $120.
Step-by-step explanation:
First you need to set up your equation. We know Jesse has $60 already and that he charges $15 per lawn. Your equation will look something like this:
15x+60=?
Then you plug in the 4 lawns he did:
15(4)+60=
Then you solve and get 120! :)
PS Parenthesis mean you are multiplying. Same thing as saying
15 x 4 + 60= 120
Can someone help I have a second chance
Answer:
rewrite equation 2 for x
x=8-7y
plug in x for equation 1
3/8*(8-7y)+1/3y=17/24
solve for y
3-17/24=21/8y-1/3y
55/24 = 55/24y
y=1
sub y back into eq. 2
x+7(1) = 8

-2x-10x+12=18
PLEASE EXPLAIN HOW YOU GOT THE ANSWER
Answer:
x = - 0.5
Step-by-step explanation:
you have to simplify the equation so
[tex] - 2x - 10x + 12 = 18 \\ - 12x + 12 = 18 \\ - 12x = 18 - 12 \\ - 12x = 6 \\ x = \frac{6}{ - 12} \\ x = - 0.5[/tex]
Answer:
X= -1/2 Hope this helps <3
Step-by-step explanation:
Let's solve your equation step-by-step.
−2x−10x+12=18
Step 1: Simplify both sides of the equation.
−2x−10x+12=18
−2x+−10x+12=18
(−2x+−10x)+(12)=18(Combine Like Terms)
−12x+12=18
−12x+12=18
Step 2: Subtract 12 from both sides.
−12x+12−12=18−12
−12x=6
Step 3: Divide both sides by -12.

The value of x is 42. Multiply the top and bottom by 6 because the numerator in the first fraction is 2 and the numerator for the second fraction is 12. When you multiply 2 by 6, you get 12. You have to do the same for the denominator. multiply 7 by 6. You get 42. The value of x is equal to 42. Hope this helps.
Answer:
42
Step-by-step explanation:
First, you cross multiply.
12 x 7= 84
2 multiplied by x will give you 2x.
Now, you have the equation below left:
84=2x
Then, you divide by 2 on both sides (in order to leave x by itself):
84/2= 42
x=42
