Answer:
Step-by-step explanation:
q+n=25
n=25-q
25q+5n=505, using n=25-q in this equation gives you
25q+5(25-q)=505
25q+125-5q=505
20q+125=505
20q=380
q=19
So 19 of the coins are quarters.
Answer:
John has 19 quarters out of 25 coins.

Alvin's age is three times Elga's age. The sum of their ages is 104. What is Elga's age?
Answer: Alvin is 78, Elga is 26
Step-by-step explanation:
Let's first start by naming the variables:
a = Alvin's age
e = Elga's age
a = 3e
a + e = 104
substitute a (in the second equation) as 3e
3e + e = 104
4e = 104
e = 26
Substitute e as 26 into either equation
a = 3(26)
a = 78

In a school, 4 out of every 7 students are girls. if there are 84 students at the school, how many are boys. AND SHOW WORKING
Answer:36
Step-by-step explanation:
[tex]\frac{4}{7} =\frac{48\\}{84}[/tex]
for every 7 students there are 4 girls, so for every 84 there must be 48
7*12=84
4*12=48
so, in all 84 students there are 48 girls
so amount of boys=84-48=36
there are 36 boys

What is the answer please
Answer:
RVS is equal to 180 - 26 degrees, or 154 degrees.
Bonus: I assume the next part of the question asks you to solve for x, where x is equal to that angle. If so, then the answer is 15:
154 = 10x + 4
150 = 10x
x = 15
Please help me solve this
Answer:
7)
to work it out:
180-110= 70
because there are two unknown angle we're gonna assume they're both the same amount. So if they are both the same and equal then we need to half 70 which will be equal to the two sided. So. 70/2= 35
So the 2 x's = 35 each
8)
you need to put this all into an equation so:
7x-11 + 5x-2 + 2x-3 = 180 degrees
12x - 9 + 2x-3
10x + 6
Actual answer:
14x-16

Solve the inequality: x/-3 < -10
Answer:
x>30
Step-by-step explanation:
x/-3<-10
x<-10*-3
x<30
x>30
Answer:
x > 30
Step-by-step explanation:
Multiply both sides by -3: This results in x > 30. Note that the direction of the inequality sign has been reversed, as is required when we multiply or divide an inequality by a negative number.

Step-by-step explanation:
A scientific calculator has 42 buttons. There are twice as many grey buttons as orange buttons. There are two more white buttons than grey buttons. There twice as many black buttons as white buttons. WRITE AN EQUATION TO CALCULATE HOW MANY BUTTONS OF EACH COLOUR THERE ARE. LET X REPRESENT THE NUMBER OF ORANGE BUTTONS.
Answer:
x + 2x + 2x + 2 + 4x + 4 = 42
Step-by-step explanation:
Let us assume the number of orange buttons be x
So, the grey buttons be 2x
The white buttons would be 2x + 2
And the black buttons be 2(2x + 2) i.e. 4x + 4
Also the total is 42 buttons
So, the equation is
x + 2x + 2x + 2 + 4x + 4 = 42

Caroline, Colin & Sarah share some money.
Caroline gets 1/9 of the money.
Colin and Sarah share the rest in the ratio 1:3.
What proportion does Sarah get?
Answer:
2 ÷ 3
Step-by-step explanation:
Let us suppose the money be 90
Since caroline gets 1 by 9 of the money i.e. 10
And, the remaining money would be distributed among Colin and sarah in the ratio of 1:3
So, the remaining money would be
= 90 - 10
= 80
So, the sarah could get
= 80 × 3 ÷ 4 ÷ 90
= 60 ÷ 90
= 20 ÷ 30
= 2 ÷ 3

PLEASE HELP
Meryl buys new baseball equipment for $2000. The purchase made is with a credit card that has a 19% APR. Meryl makes a $150 payment monthly. How many months will it take Meryl to pay off the balance?
Answer:
It will take Meryl 15.09 months to pay off the balance.
Step-by-step explanation:
This can be calculated using the formula for calculating the present value of an ordinary annuity as follows:
PV = P * ((1 - (1 / (1 + r))^n) / r) …………………………………. (1)
Where;
PV = Present value or the cost of the new baseball equipment = $2000
P = Monthly payment = $150
r = Monthly interest rate = annual percentage rate (APR) / 12 = 19% / 12 = 0.19 / 12 = 0.0158333333333333
n = number of months it will take Meryl to pay off the balance = ?
Substitute the values into equation (1) and solve for n, we have:
2000 = 150 * ((1 - (1 / (1 + 0.0158333333333333))^n) / 0.0158333333333333)
2000 / 150 = (1 - (1 / 1.0158333333333333)^n) / 0.0158333333333333
13.3333333333333 = (1 - 0.984413453650536^n) / 0.0158333333333333
13.3333333333333 * 0.0158333333333333 = 1 - 0.984413453650536^n
0.21111111111111 = 1 - 0.984413453650536^n
0.984413453650536^n = 1 - 0.21111111111111
0.984413453650536^n = 0.78888888888889
loglinearize both sides, we have:
nlog0.984413453650536 = log0.78888888888889
n = log0.78888888888889 / log0.984413453650536
n = -0.102984160720249 / -0.00682245957075587
n = 15.0948729929724
Rounding to 2 decimal places, we have:
n = 15.09
Therefore, it will take Meryl 15.09 months to pay off the balance.
three decimal numbers that when rounded to the nearest hundredths place will round to the number 6.75.

whats a reasonable estimate for 529 divided by 23 ( explain your anwser )
Step-by-step explanation:
First you divide 529 and 23. You can divide 5w9 by 23 in a fraction like this 529/23 on to Desmos scientific calculator or just 529÷23 on a calculator. If it is a decimal, round it up if the tenth, hundredth, or thousandth is 5, 6, 7, 8, 9 or round down if the number is 4, 3, 2, and 1. The answer to 529÷23 is 23. And if you estimate it, it'll be 20. The next part may be a bit confusing but if you estimate 23, you'll get 25.
Then you estimate 529 and 23, you'll get 530 and 20. And if you divide them, you'll get 26.5. And if you estimate that, you'll get 27. So that means is 2 or 7 off from the estimated from the equation 529÷23. So that means the reasonable answer is probably 25 or 27.
