Step-by-step explanation:
−8(x−1)=−32
(−8)(x)+(−8)(−1)=−32
−8x+8=−32
Step 2: Subtract 8 from both sides.
−8x+8−8=−32−8
−8x=−40

Step-by-step explanation:
2) Elena already walked 12 miles, she then walks another 1/4 of those 12 miles. The answer is A.
3) Shawn is looking for a good book, he reads 12 books and then decides to read 1/4 of the amount he already read. How many books has Shawn read in total?
4) to find the answers figure out how much they multiply one number by and multiply the other number by that amount. For example, the ratio 2:5 can be the same as 4:10 because you are multiplying the original ratio by 2 to get the new ratio.
5) The diameter of a circle is the length of one side to another. to find the length of the outer edge you need to find the circumference. To find the circumference of a circle you must use [tex]\pi[/tex]*Diameter. To find the answer we must use 180/[tex]\pi[/tex]D. Since pi can not be defined we will use 3.14 as a rough estimation. 3.14*12=37.68. 180/37.68=4.777070064. Since it doesn't make much sense to do .8 of a invitation then we must round down. The answer is 4.

In triangle ABC, the measure of angle ABC is 42 degrees and the measure of angle BAC is 64. What is the measure of angle BCA? Write an expression to find the measure of angle BCA.
Answers
Answer:
Step-by-step explanation:
The sum of interior angles of a triangle = 180°
Therefore, ∠ABC + ∠BAC + ∠BCA = 180°
⇒ 42 + 64 + ∠BCA = 180°
⇒ ∠BCA = 180 - 42 - 64

Gideon took an online math test consisting of 25
questions. Each question was worth 2
points, and Gideon scored 42
points. What percentage of the total points did Gideon score?
Answers
Step-by-step explanation:
25 questions, 2 points each.
that means there were 25×2 = 50 points in total.
Gideon got 42 out of the 50.
100% = 50
1% = 100%/100 = 50/100 = 0.5
42 is how many % ? as many as 1% (0.5) fits into 42.
so,
42/0.5 = 42×2 = 84%
he scored 84%.

Answer:
Part A: by finding equation and x value is size.
Take two coordinates: (20, 1/5), (40,2/5)
slope:
[tex]\frac{y2-y1}{x2-x1}[/tex]
[tex]\frac{\frac{2}{5} -\frac{1}{5} }{40-20}[/tex]
[tex]\frac{0.2}{20}[/tex]
[tex]0.01[/tex] ......this is slope, unit rate.
Equation:
y - y1 = m( x - x1 )
y - 1/5 = 0.01(x - 20)
y = 0.01x ........this is the equation
The y determines the size of kilowatts of energy
So y = 5
5 = 0.01x
x = 500 square feet
500 square feet is required to produce 5 kilowatts of energy.

Calculate £6.30 divided by 7.
Write your answer in pence.
Answers
Answer:
its 0.9 which is 90 I Literally divided it
Step-by-step explanation:
£6.30 divided by 7 is equal to 90 pence.
What is the division operation?In mathematics, the division operation splits left-hand operands into right-hand operands. The division's primary goal is to create equal groups or to ascertain how many individuals are in each category following a fair distribution.
For example 4/2 = 2
To convert £6.30 to pence, we multiply it by 100 because there are 100 pence in 1 pound.
£6.30 x 100 = 630 pence
Now, to calculate 630 pence divided by 7:
630 pence / 7 = 90 pence
Therefore, £6.30 divided by 7 is equal to 90 pence.
