Answer:

M = 60

Step-by-step explanation:

First, use the distributive property:

12(m + 15) = 900

12 x m = 12m

12 x 15 = 180

We get the equation 12m + 180 = 900

Subtract 180 from both sides.

12m + 180 - 180 = 900 - 180

We get the equation 12m = 720

Divide by 12 on both sides.

12m/12 = 720/12

We get m = 60

I would appreciate brainliest but if not that's ok!

Answer:

60

Step-by-step explanation:

The equation is 12m +180=900 because we already did the distributive property. So now we have to minus 180 from both sides which gets us 12m=720. Now we divide both sides by 12. So 12m/12=m and 720/12=60. This leaves us with the answer, m=60.

Answer: a. 0.6

b. 42 buttons

Step-by-step explanation:

a. What fraction of the buttons did not have 5 holes?

Since forty percent of the 70 buttons in the box had 5 holes, the number of buttons in the box that doesn't have 5 holes will be:

= 100% - 40%

= 60%

= 60/100

= 0.6

b. How many buttons did not have 5 holes?

This will be:

= 60% × 70

= 0.6 × 70

= 42 buttons

Answer:

141 campers voters for hotdogs

Step-by-step explanation:

h+ s = 188

h = 3s

3s + s = 188

4s = 188

s = 47

h = 141

The number of campers who voted for hot dogs is 141.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of campers = 188

The number of campers who voted for hot dogs.

= 3x

The number of campers who voted for spaghetti.

= x

Now,

3x + x = 188

4x = 188

x = 47

Now,

3 x 47

= 141

Thus,

141 campers voted for hot dogs.

Answer:

Number of wooden cubes in the box = 240

Step-by-step explanation:

A toy company uses the Box shown below to package wooden cubes each wooden Cube has a volume of 1/8 cubic feet in total how many wooden cubes will fit in the Box

Volume of the box = length × width × height

= 5 ft × 3 ft × 2 ft

= 30 ft³

Each wooden cube has a volume of 1/8 cubic foot

how many wooden cubes will fit in the box?

Number of wooden cubes in the box = Volume of the box ÷ volume of the wooden cube

= 30 ft³ ÷ 1/8 ft³

= 30 × 8/1

= 240

Number of wooden cubes in the box = 240

Step-by-step explanation:

Answer:

3 miles per hour

Step-by-step explanation:

Speed is defined as the distance covered per unit time, which can be expressed mathematically as follows;

Speed = Distance/Time

The given parameters are;

The length of the circular running track = 1/8 mile

The time it takes Elena to complete a lap = 1/24 hour

Therefore, we have;

Elena's running speed = The distance Elena completes/(The time it takes Elena to complete the given distance)

∴ Elena's running speed = The 1/8 mile track/(1/24 hour)

[tex]Elena's \ running \ speed =\dfrac{\dfrac{1}{8} \ mile }{\dfrac{1}{24} \ hour } = \left (\dfrac{1 }{8} \times \dfrac{24}{1 } \right ) \ \dfrac{mile}{hour} = \dfrac{24}{8} \ \dfrac{mile}{hour} =3 \ mile/hour[/tex]

Elena's running speed = 3 mile per hour.
