Lisa had four candy bars . She ate 2 3/8 of the candy bars. How many candy bars does she have left.

Answers

Answer:

1 5/8

Step-by-step explanation:

You need to do the subtraction 4 - 2 3/8.

You can use mixed numerals, but you need to borrow and you need a common denominator.

4 - 2 3/8

Since 4 has no fraction part, we borrow 1 from 4 leaving 3. The 1 we borrow becomes a fraction written as 8/8, so we have the same denominator as the fraction 3/8.

Now we have

4 - 2 3/8 =

= 3 8/8 - 2 3/8

Subtract 2 from 3 to get 1.

Subtract 3/8 from 8/8 to get 5/8.

= 1 5/8

You can also set it up vertically as shown below and then subtract the whole numbers and subtract the fractions.

y = -8x – 30
y = 2x + 150

Answers

Step-by-step explanation:

y - y = 2x + 150 -( - 8x - 30 )

0 = 2 x + 150 + 8 x + 30

0.= 10x + 180

- 180 = 10 x

-180/10 = x

-18 = x

then y = 2 (-18) + 150

y = -36 + 150

y = 114

Problem 44. The sum of a certain quantity "p" together with two-third of that number, and one-third of that number, becomes 234. What is the quantity "p"? (HINT: Write the equation out and solve)

Answers

Answer:

[tex]p=117[/tex]

Step-by-step explanation:

Given number is [tex]p[/tex].

Two-third of the number = [tex]\frac{2}{3}p[/tex]

One-third of the number = [tex]\frac{p}{3}[/tex]

The sum of a certain quantity [tex]p[/tex] together with two-third of that number, and one-third of that number, becomes 234.

[tex]p+\frac{2}{3}p+\frac{p}{3}=234\\\\\frac{3p+2p+p}{3}=234\\\\\frac{6p}{3} =234\\\\2p=234\\p=117[/tex]

identify the slope and y- intercept of the equation y = -3x

Answers

Answer: The slope is -3 and the y-intercept is (0,0)

Step-by-step explanation: Hope this helps, if it does can I get the brainliest answer

Answer:

Slope:  − 3

y-intercept:  ( 0 , 0 )

Step-by-step explanation:

The slope-intercept form is  y  =  m x  +  b.

Find the values of  m  and  b  using the form  y  =  m x  +  b .

m  =  −3 ; b =  0

The slope of the line is the value of  m , and the y-intercept is the value of  b .

Slope:  − 3

y-intercept:  ( 0 , 0 )
