Answer:

2b ÷ c + 3a = 27

Step-by-step explanation:

Given that a= 5, b= 12, and c= 2.

To solve 2b divided by c+ 3a i.e 2b ÷ c + 3a

we will need to substitute a with the value of a which is 5, substitute b with the value of b which is 12 and c with the value of c which is 2.

Therefore we will have:

2b ÷ c + 3a to be

2(12) ÷ 2 + 3(5)

= 24 ÷ 2 + 15

Recall that in order of operations BODMAS, Bracket, of, division, multiplication, addition and subtraction.

Division come in before addition

So,

= 24 ÷ 2 + 15

= 12 + 15

= 27

At what rate would u need to invest $25000 to earn $5000 in 2 years?

Vlad [161]

Answer:

The appropriate interest rate would be 10%.

Step-by-step explanation:

Without further info I must assume that you want "simple interest" on the $25000 principal. The appropriate formula for simple interest is:

i = p*r*t, where p is the principal amount, r is the interest rate as a decimal fraction, and t is the time in years.

We want the rate, r, so we solve this equation for r: r = -------------

p*t

Now we're in a position to substitute the known values of i, p and t and to calculate r from them:

$5000 1

r = ---------- ------------- = --------------- = 0.10

($25000)(2 yrs) 10

The appropriate interest rate would be 10%.

The linear equation y=-2x+4 is represented on the graph below. A second linear equation is represented by the data in the table.

atroni [7]

Answer:

The solution of the system of equations is (2,0)

Step-by-step explanation:

step 1

Find the equation of the second line

we have

y=-2x+4 ----> First equation

Find the second linear equation

we have

(-4,-3), (0,-1),(2,0),(6,2)

Find the slope m

Points (0,-1),(2,0) ---> y-intercept and x-intercept of the second equation

m=(0+1)/(2-0)

m=1/2

The equation of the line into slope intercept form is equal to

y=(1/2)x-1

step 2

Solve the system of equations

we have

y=-2x+4 ----> First equation

y=(1/2)x-1 ----> Second equation

Solve by graphing

The intersection point is (2,0)

therefore

The solution of the system of equations is (2,0)

see the attached figure

Zena and Audrey are on the same bowling team. The sum of their averages is 299. If Zena's average is 13 pins greater than Audrey

Lisa [10]

Easier than it looks, all you have to do is first subtract 13 from 299. You should get 286. Then, you just divide this number by two to get 143. Finally, since it asks for ZENA'S average, you add the 13 back to 143 to get the final answer of the average number of pins Zena took down, which is 156!
