what is 2+x/5+x=7/8?
Answer:
x = - [tex]\frac{15}{16}[/tex]
Step-by-step explanation:
2 + [tex]\frac{x}{5}[/tex] + x = [tex]\frac{7}{8}[/tex]
Multiply through by 40 ( the LCM of 5 and 8 ) to clear the fractions
80 + 8x + 40x = 35
48x + 80 = 35 ( subtract 80 from both sides )
48x = - 45 ( divide both sides by 48 )
x = - [tex]\frac{45}{48}[/tex] = - [tex]\frac{15}{16}[/tex]
Antonia bought a set of dishes, a towel, and a candle at a housewares store. The set of dishes cost $35.02, the towel cost $21.43, and the candle cost $9.59 before any coupons or discounts.
She used a $0.50-off coupon on the candle, a $2.75-off coupon on the towel, and the set of dishes was on sale for 10% off the regular price. Which of the following best describes the amounts that Antonia saved?
Answer:
Antonia saved $5.39
Step-by-step explanation:
Candle:
$9.59 - $0.50 (coupon) = $9.09
Towel:
$21.43 - $2.75 (coupon) = $18.68
Dishes:
$21.43 x 10% = 2.143
$21.43 - $2.143 = $19.287, rounded to the nearest cent and it’s $19.29.
Calculate the amount of money saved by adding 0.50 + 2.75 + 2.143, which is 5.393. Round to the nearest cent and it will be $5.39.
If a delivery truck drives 150 miles in 6 hours and maintains that rate of speed,
what is the unit rate for miles per hour?
Answer: 25 miles per hour
Step-by-step explanation:
Speed=Distance/Time
The distance is 150, and the time is 6. So, all we need to do is divide 150 by 6, and we get 25 miles per hour. Hope this helped!
Answer:
Step-by-step explanation:
r = d/t
d = 150 miles
t = 6 hours
r = 150 / 6
r = 25 miles / hour
javier went to cvs to buy bags of candy for his friends for halloween. he bought three more bags of reese's than lollipops and two fewer bags of starburst than lollipops. bags of lollipops cost $3.75 each, bags of reese's cost $5.50 each and bags of starburst cost $4.25 each. He spend a total of $48.50 and was not charged any tax. How many bags of lollipops did javier bought?
The number of bags bought by Javier will be 2.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Javier bought three more bags of Reese's than lollipops and two fewer bags of starburst than lollipops. bags of lollipops cost $3.75 each, bags of Reese's cost $5.50 each, and bags of starburst cost $4.25 each. He spends a total of $48.50.
From the equations and solve them to get the number of lollypops.
R = L+3
L = S - 2
The equation for total cost will be,
3.75L + 5.5R + 4.25S = 48.5
3.75( s - 2) + 5.5( S + 1) + 4.25S
3.75S - 7.5 + 5.50S + 5.5 + 4.25 S = 48.5
13.5S = 48.5 + 2
13.5S = 50.2
S = 4
The number of lollypops will be,
L = S - 2
L = 4 - 2
L = 2
Therefore, the number of bags bought by Javier will be 2.

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $28 monthly fee and charges an additional
50.08 for each minute of calls. The second plan has a $19 monthly fee and charges an additional $0.13 for each minute of calls. For how many minutes of calls
w the costs of the two plans be equal?
Answer:
180 minutesStep-by-step explanation:
Let x be the number of minutes of calls.
The first plan has a $28 monthly fee and charges an additional $0.08 for each minute of calls:
p(f) = 0.08x + 28The second plan has a $19 monthly fee and charges an additional $0.13 for each minute of calls:
p(s) = 0.13x + 19When p(f) = p(s) we get the following equation for x:
0.08x + 28 = 0.13x + 190.13x - 0.08x = 28 - 190.05x = 9x = 9/0.05x = 180There are 30 tickets numbered as 1, 2, 3, 4, 30 respectively. One random. What is the probability that the number on the ticket is a multiple 2 or 3
Answer:
2/3 or 66.66%Step-by-step explanation:
Out of 30 numbers, half is multiple of 2 and the third is multiple of 3.
We have 15 even numbers and 10 multiples of 3. Out of 10, half is even numbers and therefore counted twice.
So we subtract 5 to get:
15 + 10 - 5 = 20 numbersIf we chose one ticket at random the probability is:
P(2x or 3x) = 20/30 = 2/3 or 66.66%Write 50 as a product of three primes

State the equation of the line described.
A line passes through the point (-2,8) and is perpendicular to the line y = -3x + 3.
thank you guys!
Answer:
y = mx + b
Since it is perpendicular to the given line, its slope is the negative reciprocal of the slope of the given line.
Slope of given line:
m0 = -a/b = -(-3) / (1) = 3
Slope of perpendicular line:
m = -1/3
y = (-1/3)x + b
Use the given point to find b.
2 = (-1/3)(3) + b
2 = -1 + b
b = 3
y = (-1/3)x + 3
Step-by-step explanation:
Answer:
Step-by-step explanation:
Perpendicular lines have their slope negative reciprocal
y= -3x +3 has the slope -3
y = (1/3)x +b is the line that is ⊥ so it has the slope (1/3)
The line passes trough the point (x=-2, y=8) so substitute the x and y to find b
8 = (1/3)(-2) +b, multiply (1/3)(-2) = -2/3 and add 2/3 on both sides
8+(2/3) = b, find the common denominator and add the fractions
[(3*8)+2 ]/3 =b
(26/3) = b
The equation of the line described is y= (1/3)x +(26/3)

A rectangle has an area of 513.5m2. One of the sides is 7.9m in length. Work out the perimeter of the rectangle.
I will give top answer to first person who can answer and explain.
Answer:
P=145.8m
Step-by-step explanation:
Answer: The perimeter is 145.8 square meters
Step-by-step explanation:
Area=513.5 square meters
513.5=l (length) times w (width)
513.5= 7.9 times w
513.5= 7.9w
(DIVIDE 513.5 AND 7.9 BY 7.9)
65= w
Perimeter= 2l + 2w
Perimeter=2(7.9) + 2(65)
Perimeter=15.8 + 130
Perimeter=145.8 square meters
