To find the slope and y-intercept, you can convert the linear equation into the form y = mx + b, where m is the slope and b is the intercept.
To do so, just simplify for y.
18x+4y=112
4y=-18x+112
y = - \frac{18}{4}x+28
So, the y-intercept is (0, 28) and the slope is 4.5.
Hope that helps!

Drupady [299]

3 3/5 & 18/5 are both equivalent

Step-by-step explanation:

3 3/5 = 18/5

<u>Write the mixed number as an improper fraction</u>

Step 1: Multiply the denominator by the whole number

5 × 3 = 15

Step 2: Add the answer from Step 1 to the numerator

15 + 3 = 18

Step 3: Write answer from Step 2 over the denominator

18/5

Therefore, 3 3/5 is equivalent to 18/5

Miranda had 4 pounds, 6 ounces of clay. She divided it into 10 equal parts. How heavy was each part?
Mazyrski [523]

Change pounds to ounces.

1 pound = 16 ounces.

4 x 16 = 64 + 6 = 70 total ounces of clay.

Now divide by 10:

70 / 10 = 7

Each part was 7 ounces.

3 There are 5 times as many boys as girls in a school.
Dafna1 [17]

Answer:

Number of boys = 675

Step-by-step explanation:

Given that:

There are 5 times as many boys as girls in a school.

Number of pupils in school = 810

Let,

x be the number of girls

y be the number of boys

According to given statement;

x+y=810      Eqn 1

y = 5x         Eqn 2

Putting y=5x in the Eqn 1

x+5x=810

6x=810

Dividing both sides by 6

\frac{6x}{6}=\frac{810}{6}\\x=135

Putting x=135 in Eqn 2

y = 5(135)

y = 675

Hence,

Number of boys = 675
