Answer:
(8 * x) + 2x = 60
8x + 2x = 60
10x = 60
/10 /10
x = 6
8 is a constant that is being multiplied by an unknown number which we will name x. It is then being added to two times the unknown number(x), so we multiply x by 2, which is 2x. The final product will be 60, so in the equation it'll then equal 60.
We consider "a number" to be a variable that withholds an unknown value, which is x (or any other variable you prefer).
Answer:
The number is 6
Step-by-step explanation:
Given :-
8N + 2N = 60
To Find :-
N
Solving :-
8N + 2N = 60
10N = 60
N = 6
Solution :-
The number is 6

At Thomas High School, 200 students go to school by their own vehicle. If this number of students is 40% of school enrollment, then how many students are there in the school altogether?
Answer:
500 students
Step-by-step explanation:
40% = 200 students
divide both by 4 to 10%
10% = 50
multiply both by 10 to get 100%
100% = 500
or the quicker way,
200 x 2 = 400 (80%) + 100 (20%) = 500 (100%)

11. If the perimeter of the given triangle is more than 22 cm and less than or equal to 30cm. express it in inequality and solve it.
Answer:
5 < x ≤ 7
Step-by-step explanation:
perimeter = 2x + x + x + 2 = 4x + 2
perimeter is more than 22 so 22 is less than perimeter , then
22 < 4x + 2 ≤ 30 ( subtract 2 from each interval )
20 < 4x ≤ 28 ( divide each interval by 4 )
5 < x ≤ 7

Step-by-step explanation:
76, x and 63 are linear pair angles.
Sum of linear pair angles is 180,
76 + x + 63 = 180
x + 76 + 63 = 180
x + 139 = 180
x = 180 - 139

Tormod bought a perfectly square table but found out it won't fit through his study
door. To solve the problem, he reduces its width by 9cm but also extends its length by
9cm. Its new area is 309cm?
What was the area of his original square table?
Answer:
390 cm^2
Step-by-step explanation:
Let's call the dimensions of the original square x by x. Its area is x^2.
After the table is altered, its dimensions are x + 9 by x - 9, and you're given the area is 309 cm^2.
[tex](x+9)(x-9)=309\\\\x^2-81=309\\\\x^2=390[/tex]
This last equation is telling us the area of the original, square table.
You helped 3.6 customers per half hour yesterday so I helped how many customers in 7,.5 hours yesterday
Step-by-step explanation:
I guess, "you" and "I" are working with the same efficiency and work rate.
and with the typos in it, it is not clear, if I understood the problem and the given data properly.
but based on what I understood :
so, 3.6 customers in 0.5 hours.
7.5 hours × 2 = 15 times 0.5 hours.
15 × 3.6 = 54 customers.
so, with the same work rate as you, I helped 54 customers in 7.5 hours.

Answer:
$1322.67
Step-by-step explanation:
Let the total amount that Sarah deposited be $x
using the annuity formula:
A=P[((1+r)^n-1)/r]
A=future value
r=rate
n=number of years
from the information given:
A=$500000
r=2.75%
n=65-42=23 years
p=$x
thus plugging our values in the formula we get:
500000=x[((1+0.0275)^(23)-1)/(0.0275)]
500000=31.50x
x=15,872.04883
She deposited 15,873.04883 per year
The monthly deposit will therefore be:
15873.04883/12=$1322.67
