Solve and show how you did 5 (x-1) + 3 = 13
Answer:
x=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(x−1)+3=13
(5)(x)+(5)(−1)+3=13(Distribute)
5x+−5+3=13
(5x)+(−5+3)=13(Combine Like Terms)
5x+−2=13
5x−2=13
Step 2: Add 2 to both sides.
5x−2+2=13+2
5x=15
Step 3: Divide both sides by 5.
5x

Lines c and d are intersected by line p. At the intersection of lines c and p, the bottom left angle is (3 x + 45) degrees. At the intersection of lines d and p, the uppercase left angle is 81 degrees.
What must be the value of x so that lines c and d are parallel lines cut by transversal p?
12
18
81
99
The value of x so that lines c and d are parallel lines cut by transversal p is 12
Angles and transversalsFrom the given figure, the sum of the given angles is supplementary, that is:
3x + 45 = 81
Subtract 45 from both sides
3x + 45 -45 = 81 - 45
3x = 36
x = 12
Hence the value of x so that lines c and d are parallel lines cut by transversal p is 12

A and B are supplementary angles. If m A=(x-18)° and mB =(x-20),
find the measure of B
Answer:
89 degrees
Step-by-step explanation:
supplementary angles add up to 180 degrees, so we can add up A and B and make it equal to 180.
(x-18)+(x-20)=180
2x-38=180
2x=218
x=109
then, we plug in 109 for x in the mB equation.
mB=x-20
mB=109-20
mB=89 degrees
therefore, the measure of B is 89 degrees.
Answer:
B = 89
Step-by-step explanation:
Supplementary angles: A + B = 180
Simplify: x-18 +x -20 = 180
2x-38 = 180
2x = 218
x= 109
B = x-20
B = 89
Solve [X + 8) = 5
With steps
Answer:
X=(-3)
Step-by-step explanation:
1.Subtract 8 from both sides of the equation.-(x+0)=5-8-the 0 is there because the 8 on the left side is canceled out.
2.5-8 is all you have to look at.-when you look at this you know that it will be negative because 8 is on the right of the minus sign and it is greater than 5.
3.Use a calculator or you fingers to find answer.-(4,3,2,1,0,-1,-2,-3)

Answer:
38%
Step-by-step explanation:
Change [tex]\frac{7}{25}[/tex] to a percent, that is
[tex]\frac{7}{25}[/tex] × 100% = 0.28 × 100% = 28%
Then 34% + 28% = 62% ← go by bus or car, leaving
100% - 62% = 38% walking to school

in a survey, 25 out of 200 students are planning to vote for Susie for class president. If there are 1,000 students voting, how many votes would Susie expect?
Answer:

Set up a proportion.
[tex]\frac{25}{200} =\frac{x}{1000}[/tex]
Cross-multiply. Solve for x.
[tex]25,000=200x\\25,000/200 = 200x/200\\125=x[/tex]

At a carnival, food tickets cost $2 each and ride tickets cost $3 each. A total of $1,240 was collected at the carnival. The number of food tickets sold was 10 less than twice the number of ride tickets sold.
The system of equations represents x, the number of food tickets sold, and y, the number of ride tickets sold.
2x + 3y = 1240
x = 2y – 10
How many of each type of ticket were sold?

Carlo’s Bakery is having a special where he packages 6 muffins together for a low price and he packages 20 cookies together for a low price. His baker realized they sold the same amount of muffins and cookies yesterday due to this great sale. What is the minimum amount of muffins that were sole yesterday? Is this a GCF or LCM problem?
Answer:
They sold 60 muffins and 60 cookies yesterday
It is a LCM problem
Step-by-step explanation:
6 muffins together
20 cookies together
To sell the same amount of muffins and cookies,
Find the lowest common multiple of 6 muffins and 20 cookies
6 muffins = 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78
20 cookies = 40, 60, 80
The lowest common multiple of 6 muffins and 20 cookies is 60
Therefore,
They sold 60 muffins and 60 cookies yesterday
It is a LCM problem
To rent a Bird scooter you must pay $1 to start and then $0.50 for every 15 minutes you ride. Is the cost proportional to the amount of time you ride?
Step-by-step explanation:
if you rent a scooter for 15 minutes you pay $1.50 ($1 to start and $0.50 rental) and if you rent it for 30 minutes then you pay $2.00 ($1 to start and $1 rental). This is NOT proportional because $1.50/15-mins and $2.00/30-min are NOT equivalent ratios

Answer:
h = 18( I might be wrong though)
Step-by-step explanation:
If BE and ED are perpendicular, that means this angle is supplementary.
BEF = 3h-12
FED = 2h - 23
BEF + FED = 90
3h-12 + 2h - 23 = 90
5h - 35 = 90
5h = 90
h = 18 degrees
