Answer:

A 4* (7 - 3)

Step-by-step explanation:

Let's do this part by part. First we have "subtract 3 from 7:" this means we are taking 3 out of 7.

7 - 3

Next we have "then multiply by 4." So we need to take the above quantity and multiply the whole thing by 4.

(7-3) x 4

4 * (7-3)

The answer is A.

Scott wants to buy fencing to place around a semicircular rock garden The diameter of the semicircle is 16 feet Using 3.14 for p

Pavel [41]

The diameter of the semicircle is 16 feet.

He calculates that he needs to buy abut 25.12 feet of fencing.

To find amount of fencing we find the circumference of semicircle

Circumference of semicircle = $\frac{1}{2}\pi d+d$

Where d is the diameter of the circle

d= 16 given and value of pi is 3.14

Circumference of semicircle = $\frac{1}{2}*3.14*16+16$

=25.12 + 16 = 41.12 feet

Scott's calculation was wrong because he forgot to add the diameter d

Circumference of circle is half way of circle plus the diameter of circle.

Correct amount of fencing = 41.12 feet

0=2x+3(3x-4)-(-x+14) Fraction answer need help!!!

blondinia [14]

0=2x+3(3x-4)-(-x+14)
Follow BEDMAS
0=2x+9x-12-(-x+14)
0=2x+9x-12+x-14
Add like terms
0=11x-12+x-14
0=12x-12-14
0=12x-26
Flip the eqaution
12x-26=0
Move -26 across the equal sign
12x=0+26
12x=26
x=26/12
x=13/6

Hope this helps! A thanks/brainiest answer would be appreciated :)
