M(x)=4x+15;m(x)=7 Answer?

Mathematics
1 answer:
anyanavicka [17]3 years ago
6 0

Answer:

M=0

Step-by-step explanation:

(M)=4M+15(M)=7

We move all terms to the left:

(M)-(4M+15(M))=0

We add all the numbers together, and all the variables

M-(+19M)=0

We get rid of parentheses

M-19M=0

We add all the numbers together, and all the variables

-18M=0

M=0/-18

M=0

) A basketball court is 94 feet by 50 feet. Eight fans can
tatyana61 [14]

Answer:

<h2>4178kids</h2>

Step-by-step explanation:

Area of the basket ball court = Length * Breadth (since it is rectangular in nature)

Area of the basket ball court = 94 feet * 50 feet

Area of the basket ball court = 4700ft²

Area of the space covered by 8 kids = 3ft * 3ft = 9ft²

To know the number of kids that would fit the entire floor, we will use the expression;

Number of kids in the floor = 8*Area of the basket ball court /Area of the space covered by 8 kids = 8*4700/9

= 8*4700/9

= 8*522.22

≈ 4,178 kids

<em>Hence approximately 4,178 kids can fit side by side  over the entire floor</em>

To babysit one child, Fernando charges $10 to drive to the appointment plus $4 per hour. He saves 30% of the total amount he ear
sammy [17]

Th equation that can be used to determine when they would have saved the same amount is 0.3(10 + 4h) = 0.25(6h).

<h3>When would they have saved the same amount?
</h3>

The equation that can be used to determine the amount saved by Fernando is:

total amount saved = percentage saved x (amount charged to drive to the appointment + total amount earned)

0.3( $10 + $4h)

The equation that can be used to determine the amount saved by Brenna is:

percentage saved x total amount earned

0.25h

When they save the amount amount, the two above equations would be equal:  0.3(10 + 4h) = 0.25(6h).

Use factoring to write an expression that is equivalent to 25b^16-64c^2
avanturin [10]
We can write this as the difference of squares:
(5b⁸+8c)(5b⁸-8c)

To write as the difference of squares, take the square root of each term first:
√25b¹⁶ = 5b⁸; √64c² = 8c

Now we write this as a sum in one binomial and a difference in the other:
(5b⁸+8c)(5b⁸-8c)
