The number of dimes in the bag can be represented by x. The number of quarters is 6 more than twice the number of dimes. There are a total of 276 coins in the bag. What is x, the number of dimes in the bag?
Answer:
The number of dimes is represented by x = 90
Step-by-step explanation:
Given that:
The number of dimes is represented by x
Number of quarters = 6 + 2x
Total number of coins in the bag = 276
To find x, we have:
x + 6 + 2x = 276
3x + 6 = 276
3x = 276 - 6
3x = 270
x = 270/3
x = 90
PLEASE HELP ! Which inequality represents “nine more than three times a number is greater than 21”.
A. 9n > 21
B. 9+ 3 > 21
C. 3n +9 > 21
D. 9n + 3 > 21
Answer:
C
Step-by-step explanation:
Answer:
C. 3n+9>21
Step-by-step explanation:
Ignore the 9 for a second and think about the phrase "3 times a number", if we say n is the number, then 3n is 3 times the number n.
Now we need something that is 9 more than this 3n, that means you add 9 to this, so you have 3n+9.
Finally, this 3n+9 is greater than 21, so we have 3n+9>21.

A rectangle has a length of x inches and a width 2 inches less than the length. If the dimensions were doubled, what would be the area, in square inches , of the new rectangle in terms of x
Answer:
Option (4)
Step-by-step explanation:
Area of a rectangle = Length × width
If the dimensions of the given rectangle is doubled,
Area of the new rectangle = 2(Length) × 2(width)
= 4(Length × width)
= 4(x)(x - 2)
= 4[x² - 2x]
= 4x² - 8x
Therefore, Option (4) will be the correct option.

x + 5y - 10
Answer:
y = -1/5x + 2
Step-by-step explanation:
I will assume the "-" is an equal sign. Solve for y.
x + 5y = 10
~Subtract x to both sides
5y = 10 - x
~Divide 5 to everything
y = 2 - 1/5x
~Reorder
y = -1/5x + 2

Answer:
12x + 16y
Step-by-step explanation:
Multiply 4 and 3x to get 12x.
Multiply 4 and 4y to get 16y.
The sign stays positive because 4 is positive, so we end up with 12x + 16y.
Rewrite the equation C = 2nr to show the expression that can be used to find the value of r.
The process is:
C = 2nr
2nr = c
r (2n) = c
[tex]r = \frac{c}{2n} [/tex]
That's the answer☝️☝️☝️☝️
or maybe this one
r = 2n + c
sorry, I'm unsure, it has been too long since I studied that...
Answer:
C = 2nr
you divide by 2n both sides
that means C/2n = 2nr/2n
after that you simplify then it will be C/2n = r
r = C/2n

Keyla traveled 2155 kilometers by car to visit some relatives. If 1 km is approximately 0.62 miles, then what is the number of miles Keyla traveled to the nearest unit? 1,336 miles 7,471 miles 2,877 miles 3,470 miles
Answer:
1336miles.
Step-by-step explanation:
From the question we are told that;
1km represents 0.62miles
1km = 0.62miles
We are to express 2155kilometers in miles.
2155km = x miles
Find x:
Divide both equations;
1/2155 = 0.62/x
Cross multiply;
1 * x = 2155 * 0.62
x = 1,336.1miles
Hence the correct option is 1336miles.

Step-by-step explanation:
[tex] \frac{1}{4} \times 8w = 2w \\ \frac{1}{4} \times ( - 7) = \frac{ - 7}{4} [/tex]
Answer: 2w -7/4
Step-by-step explanation:
1 /4(8w − 7)
Apply the distributive property.
1 /4(8w − 7) + 1/4 ⋅ − 7
Cancel the common factor of 4.
Factor 4 out of 8w.
2w + 1/4 ⋅ -7
Combine 1/4 and -7
2w + ((-7)/4)
Move the negative in front of the fraction.
2w − 7/4
