Question 10

Agata [3.3K]

Answer:

A = 21

J = 2A = 42

C= A+5 =26

Step-by-step explanation:

C= christines text messages

J = jims messages

A = ali messages

Jim sent 2 times as many messages as Ali.

J = 2A

Ali sent 5 fewer messages than Christine.

A =C-5

A+5 =C

Christine, Jim, and Ali sent a total of 89 text messages

C+J+A = 89

substitute

C +5= A

A+5 +J+A = 89

combine like terms

2A +5+J = 89

now substitute J = 2A

2A +5+2A = 89

combine like terms

4A +5 = 89

subtract 5 to each side

4A +5-5 = 89-5

4A = 84

divide by 4

A = 21

J = 2A = 42

C= A+5 =26

How much does a glass cube with a side of 5-cm weigh if 1cm3 of glass weighs 2 2/5 grams?

PtichkaEL [24]

The weight of galss cube with side 5 cm is 300 grams

Solution:

A glass cube is of side length 5 cm

Let us first find the volume of glass cube

The volume of cube is given as:

$volume = (side)^3\\\\volume =5^3 = 125$

Thus volume of cube is 125 $cm^3$

Given that,

$1 cm^3 = 2\frac{2}{5} \text{ grams }\\\\1 cm^3 =\frac{12}{5} \text{ grams}$

So, weight of 125 cubic centimeter of glass cube is found by multiplying weight of 1 cubic centimeter of glass cube by 125

$\text{ Weight of 125 } cm^3 \text{ cube } = \text{ Weight of 1 } cm^3 \text{ cube } \times 125$

$\text{ Weight of 125 } cm^3 \text{ cube } = \frac{12}{5} \times 125 = 25 \times 12 = 300$

Thus weight of galss cube with side 5 cm is 300 grams
