Multiply each term by k k and simplify. T 5 k 3 − 2 3 = 7 k 5k3-23=7k Move all terms containing k k to the left side of the equation. Tap for more steps... − 2 ( 8 k + 1 ) 3 = 0 -2(8k+1)3=0 Multiply both sides of the equation by − 3 2 -32. − 3 2 ⋅ ( − 2 ( 8 k + 1 ) 3 ) = − 3 2 ⋅ 0 -32⋅(-2(8k+1)3)=-32⋅0 Simplify both sides of the equation. 8 k + 1 = 0 8k+1=0 Subtract 1 1 from both sides of the equation. 8 k = − 1 8k=-1 Divide each term by 8 8 and simplify. k = − 1 8 k=-18 The result can be shown in multiple forms.

Bella's Bakery charges $2.25 per cupcake
and $1.75 per cookie. A customer came in
and ordered 5 cupcakes, some cookies,
another cupc
e and paid $24. Write and
solve an equation to determine how many
cookies they purchased.
Answer:
6 cookies
Step-by-step explanation:
first, find how much money they spent on cupcakes
6 × $2.25 = $13.5
then, take $13.5 and subtract that by $24
$24 - $13.5 = $10.5
so the person spent $10.5 on cookies. divide the amount per cookie by $10.5
$10.5 ÷ $1.75 = 6
so they bought 6 cookies

Find the shortest length of wood that can be cut into equal lengths of 3m. 8
and 12m
Answer:
24
Step-by-step explanation:
Find LCM of 3 8 and 12
(calculation attached)
lcm = 3 x 2 x 2 x 2 = 24
i hope im right!
The shortest length of the wood will be 24 meters.
The Least Common Multiple (LCM) refers to the common multiple that is the least (smallest) among all possible multiples for both numbers. Calculating this least common multiple for numbers is made easier by the LCM formula.
Given that the length of the wood is 3m, 8m, and 12 m. The shortest length will be calculated by taking the least common factor of the given lengths 3m, 8m, and 12 m.
The least common factor is calculated as:-
3 = 3 x 1
8 = 2 x 2 x 2
12 = 2 x 2 x 3
LCM = 3 x 2 x 2 x 2 = 24
Hence, the shortest length of the wood will be 24 meters.

Charlotte and Riley walked 6/10 of a mile to school one day, and then after school they walked 3/8 of a mile to the store. From the store back home was another 2/5 of a mile. How far did the girls walk in all?
Answer: The girls walked [tex]1\dfrac38[/tex] miles.
Step-by-step explanation:
Given: Distance from home to school = [tex]\dfrac{6}{10}[/tex] mile
Distance from school to store = [tex]\dfrac38[/tex] mile
Distance from store to home = [tex]\dfrac25[/tex] miles
Total distance = [tex]\dfrac6{10}+\dfrac38+\dfrac25[/tex]
= [tex]\dfrac{6\times4+3\times5+2\times8}{40}[/tex] [L.C.M.(10,8,5)=40]
= [tex]\dfrac{24+15+16}{40}[/tex]
= [tex]\dfrac{55}{40}[/tex]
= [tex]\dfrac{11}{8}=1\dfrac38[/tex] miles
Hence, The girls walked [tex]1\dfrac38[/tex] miles.

Find the slope of the line parallel to the line passing through the given points: (-2, 8) and (-6, 6)
Answer:
2
Step-by-step explanation:
Use the points to find the slope, using the formula (y2 - y1) / (x2 - x1).
[tex]= \frac{-6-(-2)}{6-8}[/tex] = -4/-2 = 2
Since it's just asking for the slope, the answer is 2 (any parallel lines have the same slope).

The expression [tex]\sqrt[3]{48}[/tex] can be written as
[tex]\sqrt[3]{48}=\sqrt[3]{8\cdot 6}[/tex]
[tex]\sqrt[3]{48}=\sqrt[3]{8}\cdot \sqrt[3]{6}[/tex] [tex][\because \sqrt[3]{ab}=\sqrt[3]{a}\sqrt[3]{b}][/tex]
[tex]\sqrt[3]{48}=2\cdot \sqrt[3]{6}[/tex]
