\\ \sf\longmapsto 2(3x-7)+4(3x+2)=6(5x+9)+3

\\ \sf\longmapsto 6x-14+12x+8=30x+54+3

\\ \sf\longmapsto 6x+12x-14+8=30x+57

\\ \sf\longmapsto 18x+6=30x+57

\\ \sf\longmapsto 30x-18x=6-57

\\ \sf\longmapsto 12x=51

\\ \sf\longmapsto x=\dfrac{51}{12}

Diano4ka-milaya [45]

Answer:

The volume of the cart will be 24 ft^3

Step-by-step explanation:

The first thing we need to calculate for this question is the number of boxes that fill the entire cart.

A layer of boxes consists of 8 boxes.

The cart holds a maximum of 3 layers of boxes.

So, the total number of boxes held by the cart are:

Total boxes = number of layers * boxes per layer

Total boxes = 3 * 8

Total boxes = 24

Since each box has a volume of one cubic foot, the total volume of the cart will be:

Volume of cart = number of boxes * volume of each box

Volume of cart = 24 * 1

Volume of cart = 24 ft^3

If you have 16 cups of sugar , 2 cups of sugar for every batch of cookies , but you have to save 6 cups of sugar for something e
sesenic [268]
The first step we want to take here is to subtract 6 cups of sugar since we'll need it for something else, leaving us with 10 cups of sugar. It takes 2 cups of sugar for every batch of cookies, so you're going to divide 10 by 2. Luckily, 2 is a multiple of 10 so it's a whole number. By dividing, we get 5. So, we can make 5 batches of cookies while still saving 6 cups of sugar for something else.

tester [92]

Answer: 10

Step-by-step explanation:

Given : The American Lung Association stated that approximately 1 out of every 20 deaths in the US last year was from lung cancer.

Then, the proportion of death will be :_

p=\dfrac{1}{20}=0.05

Now, If there are 200 students in a class,  then the expected number of persons die from lung cancer :-

p\times200\\\\=(0.050)\times200=10

Hence, we expect the number of persons die from lung cancer =10
