I hope this helps
Step-by-step explanation:
So the way to handle a problem like this is to rewrite the three numbers in terms of their relationship to one of the three numbers. Let's call the numbers x, y, and z, where x is the first number, y is the second, and z is the third.
We know x + y + z = 83.
Since the third number is twice the second, we say that z = 2y.
Since the second number is seven less than the first, we say that y = x - 7. We can rewrite this as x = y + 7.
Now all three can be written in terms of y.
x + y + z = 83
(y + 7) + y + 2y = 83
4y + 7 = 83
4y = 76
y = 19
The second number is 19. The first is 19 + 7 or 26, and the third is 2 times 19 or 38.
A check reveals that 26 + 19 + 38 = 83.
Simplify the expression by combining like terms: -3+7c+c+7+10
Answer:
21 + 2c
Step-by-step explanation:
-3 + 7 + 7 + 10 = 21
c + c = 2c

what is 9/32 + 7/8 plz help
Answer:
1 5/32
Step-by-step explanation:
First, find common denominators. What you do to the denominator, you must do to the numerator.
First, multiply 4 to both the numerator and denominator of the second fraction:
(7/8)(4/4) = (7 * 4)/(8 * 4) = 28/32
Next, add across:
9/32 + 28/32 = 37/32
Simplify. Turn the improper fraction into a mixed fraction:
37/32 = (32 + 5)/32 = 1 5/32
1 5/32 is your answer.
~
Answer:
37 /32
Step-by-step explanation:
Find the least common denominator or LCM of the two denominators:
LCM of 8 and 32 is 32
For the 1st fraction, since 8 × 4 = 32,
7 /8 = 7 × 4
8 × 4 = 28 /32
Likewise, for the 2nd fraction, since 32 × 1 = 32,
9 /32 = 9 × 1
32 × 1 = 9 /32
Add the two fractions:
28 /32 + 9/32 = 28 + 9 /32 = 37 /32
So, 7/8 + 9/32 = 37/32
In mixed form: 1 5 /32

Round 543,539 to the nearest hundred thousand
Answer:
500,000
Step-by-step explanation:
The nearest hundred thousand is the first 5
In rounding when something is 4 or lower it becomes a zero and if it is 5 or higher it is goes up to the next number for example if it is rounded to the nearest ten, and the number is 338, it would be 340

find the simple interest on each amount 1500 at 11% for two years
Answer:
330.00
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 11%/100 = 0.11 per year,
then, solving our equation
I = 1500 × 0.11 × 2 = 330
I = $ 330.00
The simple interest accumulated
on a principal of $ 1,500.00
at a rate of 11% per year
for 2 years is $ 330.00.
Divide.
511÷411

Which equation shows how to rewrite the sum of 30 and 45 using their greatest common factor? 30 + 45 = 5(6 + 9) 30 + 45 = 15(2 + 3) 30 + 45 = 5(6) + 15(3) 30 + 45 = 5(6)(3)
Answer: 30 + 45 = 15(2 + 3)
Step-by-step explanation:
The greatest common factor for 30 and 45 will be gotten as follows:
Factor of 30 = 2 × 3 × 5
Factor of 45 = 3 × 3 × 5.
GCF = 3× 5 = 15
Therefore, the equation that shows how to rewrite the sum of 30 and 45 using their greatest common factor will be:
30 + 45 = 15(2 + 3)

Step-by-step explanation:
In number 2, when it comes to exponents like that, you're supposed to multiply em, nd when u do that, u get 12. It said find the sum, so u add 12 nd 2 nd get 14.
In number 3, u basically gotta find the area nd that's jus multiplyin 6 x 10 (to the 3rd power) by itself, nd that's the answer u get.

Reggie is deciding when to go bowling with his friends. Friday night is glow-bowling night,
with 5 glow-bowling games for $22.50. But the early-bird special on Saturday morning offers
8 games for $30. How much more does glow-bowling cost per game?
Answer:
glow bowling costs $0.75 more per game
Step-by-step explanation:
1. divide $22.50 by 5 games to find the price per game for glow-bowling, which comes out to $4.50
2. divide $30.00 by 8 games to find the price per game for the early-bird special, which comes out to $3.75
3. subtract $3.75 (early-bird bowling) from $4.50 (glow-bowling) and it = $0.75
4.50-3.75=0.75
Answer: The answer is 0.75
