If Jessie is 24 years younger than her mother and if the sum of their ages is 84, how old is Jessie?

8_murik_8 [283]

J + m = 84
j = m - 24

m - 24 + m = 84
2m - 24 = 84
2m = 84 + 24
2m = 108
m = 108/2
m = 54...the mom is 54

j = m - 24
j = 54 - 24
j = 30 <==== Jessie is 30

Heather, Deon, and Ali served a total of 106 orders. Deon served 4 times as many as Ali. Heather served 10 more orders then Ali.

Sergeeva-Olga [200]

Answer:

Ali served 16 orders, Deon served 64 orders, Heather served 26 orders.

Step-by-step explanation:

Let order served by

Heather be h

Deon be d

Ali be a

We can write 3 equations from the word problem:

h + d + a = 106

d = 4a

h = 10 + a

We put 2nd and 3rd equation in first and solve for a:

h + d + a = 106

10 + a + 4a + a = 106

6a = 96

a = 16

Now,

d = 4a = 4(16) = 64

and

h = 10 + a = 10 + 16 = 26

Ali served 16 orders, Deon served 64 orders, Heather served 26 orders.

A candle maker has 4 1/2 pounds of clear wax. He wants to cut the wax into pieces that are 2/3 pound each. How many 2/3 pound pi

maks197457 [2]

$\bf \cfrac{4\frac{1}{2}}{\quad \frac{2}{3}\quad }\implies \cfrac{\frac{4\cdot 2+1}{2}}{\quad \frac{2}{3}\quad }\implies \cfrac{\frac{9}{2}}{\quad \frac{2}{3}\quad }\implies \cfrac{9}{2}\cdot \cfrac{3}{2}\implies \cfrac{27}{4}\implies 6\frac{3}{4}
\\\\\\
\textit{so, 6 whole pieces, and }\frac{3}{4}\textit{ of another one}$

now, what's the leftover? well, 3/4 of the last one, namely 3/4 of 2/3, what is 3/4 of 2/3 anyway? well, is just their product,

$\bf \cfrac{\underline{3}}{4}\cdot \cfrac{2}{\underline{3}}\implies \cfrac{2}{4}\implies \stackrel{lbs}{\cfrac{1}{2}}$
