Answer:

Step-by-step explanation:

First, let's get common denominators for both fractions -- in this case, the least common multiple of $4$ and $6$ is $12$ .

$-\frac{15}{4}b + \frac{5}{6}b$

$-\frac{45}{12}b + \frac{10}{12}b$

Combining the terms together by adding the numerators will give us the answer:

$\frac{-45 + 10}{12}b$

$-\frac{35}{12}b$

The circumference of a circle is 19π ft. What is the area, in square feet? Express your answer in terms of \piπ

Alisiya [41]

Answer:

1134.1 [cm²]

Step-by-step explanation:

A=πr2

Circle area = π * r² = π * 361 [cm²] ≈ 1134.1 [cm²]

π ≈ 3.14159265 ≈ 3.14

d = r * 2 = 19 [cm] * 2 = 38 [cm]

Solve the equation. Round to the nearest thousandth. -12e-x + 8 = 7

Marysya12 [62]

Answer:

-12e-x + 8 = 7

-12e-x = 7-8

-12e-x = -1

12e-x = 1

e-x = 1/12

ln(e-x) = ln(1/12)

x = -ln(1/12)

x = -2.485

When figuring out the amount of mulch would be needed for Alex's back yard, he created an equation that

soldier1979 [14.2K]

Answer:

Alex will need 14 bags

Step-by-step explanation:

B= 4(2x+7)+3(2x+7)

and

2x+7=2

First, we should solve the second equation to obtain x:

2x+7=2

2x=2-7

x= -5/2

Then, we use this answer to calculate B:

B=4(2(-5/2)+7)+3(2)

B=4(-5+7)+6

B=4(2)+6

B=8+6

B=14

Alex will need 14 bags
