5q + 8r = 86
Find for r and q
Answer:
r=7 q=6
Step-by-step explanation:
15q - 4r = 62
15 × 6 - 4 × 7 = 62
90 - 28 = 62
5q + 8r = 86
5 × 6 + 8 × 7 = 86
30 + 56 = 86

Step-by-step explanation:
which number is the same as for the power of negative 1 * 2 ^ 8 / 4 ^ -2
A) -2
B) 1/5
C) 2
D) 32
E) 512
Answer: D) 32
Step-by-step explanation:
To solve the expression (4 to the negative power of 1)(2 to the 3rd power divided by 4 to the negative power of 2), we can follow these steps:
Step 1: Simplify 4 to the negative power of 1
4 to the negative power of 1 can be written as 1/4 to the positive power of 1, so the expression becomes: (1/4)(2 to the 3rd power divided by 4 to the negative power of 2)
Step 2: Simplify the division of powers of 4
When dividing powers with the same base (in this case, 4), we can subtract the exponents. So, 4 to the negative power of 2 is the same as 1/4 to the power of 2, which equals 1/16. The expression now becomes: (1/4)(2 to the 3rd power divided by 1/16)
Step 3: Simplify 2 to the 3rd power 2 to the 3rd power is 2x2x2, which equals 8. The expression now becomes: (1/4)(8 divided by 1/16)
Step 4: Simplify the division
Dividing by a fraction is the same as multiplying by its reciprocal. So, we can rewrite the expression as: (1/4)(8 x 16)
Step 5: Multiply 8 x 16 equals 128, so the expression simplifies to: (1/4)(128)
Step 6: Simplify the final expression
Multiplying 1/4 by 128 gives us 32. Therefore, the final answer is: 32

Answer:
14)$9,320.00. 15)Chen has 8 nickels, 2 dimes, and 6 quarters. 16)10%
Step-by-step explanation:
14)A = $9,320.00
I = A - P = $1,320.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year.
Solving our equation:
A = 8000(1 + (0.055 × 3)) = 9320
A = $9,320.00
The total amount accrued, principal plus interest, from simple interest on a principal of $8,000.00 at a rate of 5.5% per year for 3 years is $9,320.00.
16)R = 1011.1111%/year
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving our equation:
r = (1/1)((1250/112.5) - 1) = 10.11111111
r = 10.11111111
Converting r decimal to R a percentage
R = 10.11111111 * 100 = 1011.1111%/year
The interest rate required to get a total amount, principal plus interest, of $1,250.00 from simple interest on a principal of $112.50 over 1 years is 1011.1111% per year.

Which inequality shows that Jerome wants to have read at least 85 pages by the end of Friday
Answer:
50 + 5p ≥ 85
Step-by-step explanation:
I did it on I-ready
If Jerome wants to have read at least 85 pages by the end of the day on Friday, then the inequality that represents the situation will be 50 + 5p≥ 85
What is inequality?An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
here, we have,
Given that
the number of pages he read each day is "p", the number of pages he will read from Monday to Friday is 5p (Monday to Friday is 5 days)
If he has read 50 pages of a novel, the total number of books he has read will be 50 + 5p
If Jerome wants to have read at least 85 pages by the end of the day on Friday, then the inequality that represents the situation will be 50 + 5p≥ 85

Isaac and Juanita are collecting apple to make an apple pie. Isaac picks up 3 apples every minute and Juanita picks up 5 apples every two minutes. If they need 40 apples for a pie, about how long will it take both of them to collect enough apples?
Answer:
It will take them roughly 7.27 mintues
Step-by-step explanation:
To find this, model the amount of apples that can collect a minute using m as the minutes.
Isaac = 3m
Juanita = 5m/2
Now we can add them together and solve for when they will have 40 apples.
3m + 5m/2 = 40
5.5m = 40
m = 7.27
Answer:
about 7 minutes (7.27 minutes to be exact)
Step-by-step explanation:
Since they are working as a team, we can combine the two rates to see how many apples they collect together per minute. Isaac collects 3 p/min while Juanita collects 2.5 p/min equaling 5.5 apples p/min. 40 apples divided by 5.5 equals 7.27 minutes.
Hope that helped!!

What is the sum of the expression for N = -2 and M = 5?
Part B.
Which expression shown is equivalent to the sum of the two original expressions written in standard form?
-3m + 9n -10
10m - 4n - 10
-4mn
9n - 3m + 10
Answer:
E
Step-by-step explanation:
The expression that is shown -3m + 9n -10 will be equivalent to the sum of the two original expressions written in standard form.
What are equivalent expressions?Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.
We need to the expression into an equivalent form.
Therefore, (3m + 2n - 6) + (-4 -6m + 7m)
= -3m + 9n -10
Hence, the sum of the expression is -3m + 9n -10
Now we put in n = -2 and m = 5 and evaluate the expression;
-3m + 9n -10
-3(5) + 9(-2) -10 = -43
Hence, the expression that is shown -3m + 9n -10 will be equivalent to the sum of the two original expressions written in standard form.
