4(4x+3)=19x+9-3x+3 what are the steps

1 answer:

4 0

Ok so:

4(4x+3) = 19x + 9 - 3x +3
parenthesis first:
4 x 4x = 16x then 4 x 3 = 12

16x + 12 = 19x + 9 - 3x + 3
combine :) :
19x - 3x = 16x then 9 + 3 = 12

16x + 12 = 16x +12
-12 -12
16x = 16x
They are the same equations lol they equal 0.

Small notebooks cost $3.50 and large notebooks cost $5.00. She needs to buy 31 notebooks, and she has $134 to spend. How many sm

Darina [25.2K]

Let's assume

number of small notebooks =x

number of large notebooks =y

we are given

total number of notebooks =31

so, we get

$x+y=31$

now, we can solve for y

$y=31-x$

we have

Small notebooks cost $3.50 and large notebooks cost $5.00

she has $134 to spend

so, we get

$3.50x+5y=134$

now, we can plug y

$3.50x+5(31-x)=134$

$3.50x+5*31-5x=134$

$-1.5x+155=134$

$-1.5x+155-155=134-155$

$x=14$

now, we can find y

$y=31-14$

$y=17$

so,

number of small notebooks is 14

number of large notebooks is 17.............Answer
