Fill in the blanks to complete the area model to solve 6.60 divided by 15 is the same as _ x ? = _ 6.60 = _ hundredths

storchak [24]

Answer:

$15 x = 6.60$

$x = 44\ hundredths$

Step-by-step explanation:

Given

$\frac{6.60}{15}$

Required

Complete the model

[ ] x = 6.60

x = _ hundredths

$\frac{6.60}{15}$

Equate to x

$x = \frac{6.60}{15}$

Multiply both sides by 15

$15 * x = \frac{6.60}{15} * 15$

$15 * x = 6.60$

$15 x = 6.60$

So, we have:

[ ] x = 6.60 =====> $15 x = 6.60$

Recall that:

$x = \frac{6.60}{15}$

$x = 0.44$

This implies that:

$x = 44\ hundredths$

Hence:

x = _ hundredths =====> $x = 44\ hundredths$

Lena will use 7 cups of apples to make 4 batches of applesauc. Which expression shows the number of cups of apples in each batch

astraxan [27]

Answer: 1 3/4 cups of apples in each batch

Step-by-step explanation:

STEP 1

Writing out the equation to represent if 7 cups of apples make 4 batches One batch is as a result of how many cups of apples

LET x be number of cups of apples to make each batch

7 cups of apples = 4 Batches

x cups of apples = 1 Batch

STEP 2 Solving by cross multiplication

1 batch x 7 cups of apples = 4 batches X x cups of apples

x cups of apples=1 batch x 7 cups of apples / 4batches

x = 7 / 4 = 1 3/4

number of cups of apples to make each batch= 1 3/4

Adam jogs at an average speed of 10km/h from his house to the airport. The airport is 7km away from his house. At what time must

mote1985 [20]

Answer:

6:38am

Step-by-step explanation:

From the question we are told that

Average speed $V_{avg}=10km/h$

Distance traveled $d=7km$

Generally the velocity across a distance is mathematically given given as $V=d/t$

$10=\frac{7}{t}$

$t=0.7h\\t=42minutes$

Therefore

7:20-42 minutes =6:38am

If f(x) = 3x +9 x when f(x) = 30

den301095 [7]

Answer:

$x=5/2$

Step-by-step explanation:

When $f(x)=30$ , we have $3x+9x=30$ .

Combining like terms on the right side, we have $12x=30$ .

Finally, dividing by $12$ we get $x=30/12$ .

We note that $30=6*5$ and $12=6*2$ , so $30/12=5/2$ .

So, $\boxed{x=5/2}$ and we're done!
