-1-(+4)=
solve the brackets first - + = -
=-1-4
=-5

-1+(-4)=-1-
solve the left side
-1-4=-1-
-5=-1-
now think what will be -5 if we -1 from it
-5=-1-4
-5=-5

-1- =-5
-1 minus what will be -5
-1-4=-5
-5=-5

1-(-4)=1+4
dove brackets first - -=+
1+4=1+4
5=5

Simply the product -7x/5y * 5x/-7

ch4aika [34]

We are asked to simplify the expression $\frac{-7x}{5y} \cdot \frac{5x}{-7}$ ,

what we do is, we form a single fraction where the numerator is the product of the numerators, and the denominator is the product of the denominators, that is:

$\frac{-7x}{5y} \cdot \frac{5x}{-7}= \frac{-7\cdot5 \cdot x \cdot x}{5 \cdot(-7) \cdot y}$

simplify the common numbers and terms in the numerator and denominator:

$\frac{-7\cdot5 \cdot x \cdot x}{5 \cdot(-7) \cdot y}=\frac{5 \cdot x \cdot x}{5 \cdot y}=\frac{x \cdot x}{y}= \frac{ x^{2} }{y}$

Answer: $\frac{ x^{2} }{y}$

Fred has a bag of coin with only nickels and quarters. He got $20 by

Sedbober [7]

Answer:

75 quarters 25 nickels

Step-by-step explanation:

q=quarters n=nickels

q+n=100 n=100-q

0.25q +0.05(100-q)=20

From now I will multiply by 100 to avoid decimals

25q + 5(100-q)=2000

20q=1500

q=75 n=25

75*0.25= 18.75

25*0.05=1.25

18.75+1.25=20

Marco has a jug with 37 1/2 ounces of juice.He wants small cups to give samples of the juice. each cup can hold 2 1/2 ounces of

Rom4ik [11]

Turn both fractions into mixed fractions resulting in 75/2 and 5/2. Then turn them into decimals. 75/2= 37.5 and 5/2= 2.5. Then divide each other 37.5 / 2.5= 15. 15 is your answer. Hope it helped :)
