Solving two-step equations:

aleksklad [387]

Answer:

Mia scored 6 baskets Last Saturday.

Step-by-step explanation:

Let:

Mia made score of baskets on Last Saturday = x

Mia made score of baskets yesterday = 3x (Mia made three times as many baskets in yesterday’s basketball game as she did last Saturday. three times means multiply 3 with score of Last Saturday baskets, i.e. x)

Total score of baskets = 24

We need to find How many baskets did Mia score last Saturday?

We can write:

<em>Total Score = Score on Last Saturday + Score yester</em>day

$24=x+3x$

Solving this equation we can find value of x:

$24=x+3x\\24=4x\\=>4x=24\\x=\frac{24}{4}\\x=6$

So, we get value of x = 6

Mia made score of baskets on Last Saturday = x = 6

Mia scored 6 baskets Last Saturday.

A prism with a base area of 8 cm² and a height of 6 cm is dilated by a factor of 5/4 .

Andrei [34K]

The volume of the original prism is calculated by multiplying the area of the base by the height,
volume = (8 cm²)(6 cm) = 48 cm³
By the word dilated we mean to say that the dimensions of the new prism is 5/4 times that of the original solid. If we let x be the volume of the new solid,
x / 48 cm³ = (5/4)³
The value of x from the equation above is equal to 93.75 cm³.
