Answer:

(9, -15)

Step-by-step explanation:

First, label the 2 equations:

-10x -6y= 0 -----(1)

-4x -6y= 54 -----(2)

(2) -(1):

(-4x -6y) -(-10x-6y)= 54 -0

-4x -6y -(-10x) -(-6y)= 54 (expand, simplify)

-4x -6y +10x +6y= 54 (expand)

10x -4x= 54 (simplify)

6x= 54

x=54 ÷6

x= 9

susbt. x=9 into (1):

-10(9) -6y=0 (subst. x=9 into -10x-6y=0)

-90= 6y (bring y term to the other side)

6y= -90

y= -90 ÷6

y= -15

Thus, the solution is (9, -15).

Estimate the percent of each number. 47% of 77
Anettt [7]

ANSWER

36 .19

EXPLANATION

We want to estimate

47\% \: of \: 77

This is the same as

\frac{47}{100}  \times 77

or

\frac{47}{100} \times  \frac{77}{1}

We multiply the numerators to get,

\frac{3619}{100}

We convert to decimals to get

36.19
