Answer:
we are given
total number of students =23
the additional number of cookies =x
you have baked 12 cookies
so, total number of cookies =x+12
the additional number x of cookies you need to bake in order to have 2 cookies for each student
so, we can find total number of cookies
total number of cookies = ( total number of students)*(cookies each student)
so, we can plug values
total number of cookies = ( 23)*(2)
total number of cookies = 23*2
so, we can set them equal
x+12=23*2x+12=23∗2
we can divide both sides by 23
\frac{x+12}{23} =2
23
x+12
=2
so, the equation is :
\frac{x+12}{23} =2
23
x+12
=2
now, we can solve for x
Subtract both sides by 12
x+12-12=46-12x+12−12=46−12
x=34x=34
so,
the additional number of cookies is 34.......... it
Answer:
Gemma made $34 more than Leah.
Step-by-step explanation:
Gemma made number of beaded necklaces = 106
Leah made 39 more necklaces than Gemma.
Leah made number of beaded necklaces = 106 + 39 = 145
a. There are 104 beads on each necklace.
The total number of beads used altogether
= (106 × 104) + (145 × 104)
= 11,024 + 15,080
= 26,104
b. Gemma sold her 106 necklaces for = $14
Total price of her necklaces = 106 × 14
= $1,484
Leah sold her 145 necklaces for = $10
Total price of her necklaces = 145 × 10
= $1,450
Difference in Gemma and Leah's amount = 1484 - 1450 = $34.00
Therefore, Gemma made $34.00 more money than Leah.
Answer:
<u>3 4/5</u>
Step-by-step explanation:
19/5 is improper because the numerator is larger to the denominator. If we round 19 down to 15 and divide 15 by 5 we get 3 but we still have 4 left because of how we rounded it. Let me explain this a little bit smaller.
19 fits into five three times, and that leaves 4 left over, 19/5 = <u>3 & 4/5</u>
( i just added the & sign so it didn't look like 34/5 )
Answer:
3x - 2 = 4x + 5
3x - 4x = 2 + 5 (move the numbers with the variable x to one side, and the normal numbers to the other side. Switch the signs of the numbers you move. 4x became -4x and -2 became 2.)
-x = 7 (simply add the numbers)
x = 7
