Answer:

She has 20 quarters.

Step-by-step explanation:

Alissa emptied her piggy bank for Disney world. She had $7.70.

If she had 10 pennies and twice as many times as quarters, then we can write the equation as

Q = 2P {Where, Q represents the number of quarters and P for pennies}

⇒ Q = 10 × 2

⇒ Q = 20

So, she has 20 quarters.

Therefore, she has 20 quarters. (Answer)

What property of equality would you use to solve the equation n/4 = 16.
Triss [41]

Answer:

Multiplication Property of Equality.

Step-by-step explanation:

Isolate the variable, n. Note the equal sign, what you do to one side, you do to the other.

Multiply 4 to both sides of the equation:

(n/4) * 4 = (16) * 4

n = 16 * 4

n = 64

n = 64 will be your answer.

1. Now consider equations of the form , where a, b, and c are all positive integers and . (a) Create an equation of this form th
tino4ka555 [31]

a) To create an equation

X+X =7

so what's X over here is

7² = x²

X=3.5

b) Real numbers are mixture of irrational and rational numbers so √5 and √6 are irrational where as 5 and 6 are not but they two are equal to each other.

Explaining the equation:

√5 +√6 = √11

5 +6 = 11

√11 =11

√= 11 ÷ 11

√= 1

So if root is 1 then -1 is -√

this is the answer propably

A=1/2b(c+d) solve for c
TiliK225 [7]

Answer:

c = \frac{2A}{b} - d

Step-by-step explanation:

Multiply both sides by 2 to eliminate the fraction

2A = b(c + d) ← divide both sides by b

\frac{2A}{b} = c + d ← subtract d from both sides

\frac{2A}{b} - d = c

spayn [35]

Answer:

If she started with a nickel, a dime, a quarter, a half-dollar, and a dollar, she started with $1.90, which is to say 190 cents.

If she takes away one of the coins she either has 185, 180, 165, 140, or 90 cents remaining. Only one of those numbers is evenly divisible by 7.
