A total of $20,000 is to be invested, some in bonds and some in certificates of deposit (CDs). If the amount invested in bonds i

Brilliant_brown [7]

Answer:

$8,500 in CDs; $11,500 in bonds

Step-by-step explanation:

Let c = amount invested in CDs.

Let b = amount invested in bonds.

"A total of $20,000 is to be invested, some in bonds and some in certificates of deposit (CDs)."

From the total investment, we get this equation.

c + b = 20000

"If the amount invested in bonds is to exceed that in CDs by $3000"

From the details of the amounts, we get this equation.

b = c + 3000

We have a system of equations in two unknowns.

c + b = 20000 Eq. 1

b = c + 3000 Eq. 2

Since Eq. 2 is already solved for b, we will use the substitution method to solve the system of equations.

Substitute b in Eq. 1 with c + 3000.

c + c + 3000 = 20000

2c + 3000 = 20000

2c = 17000

c = 8500

Now substitute c = 8500 in Eq. 2 and solve for b.

b = c + 3000

b = 8500 + 3000

b = 11500

Answer: $8,500 in CDs; $11,500 in bonds

Please help on this asap

Lelechka [254]

I believe that would be the last choice, because it is not impossible that someone without contacts or glasses would be chosen. And it is a fairly similar chance that someone with glasses or with contacts will be chosen. Hope this helps! :)

Answer:

Step-by-step explanation:

step 1

Find out the total ball bearing ordered

Multiply the number of ball bearing boxes by the number of ball bearings in each box.

$17(85)=1,445\ ball\ bearings$

step 2

Find out the total springs ordered

Multiply the number of spring boxes by the number of springs in each box.

$15(90)=1,350\ springs$

step 3

To find out how many more ball bearings than springs did they order, subtract the total number of springs from the total number of ball bearings

$1,445-1,350=95$

Solve for x: one over four (4x + 15) = 24

Komok [63]

Answer:

x = 81/4

Step-by-step explanation:

multiply both sides by 4

4x + 15 = 96

subtract 15 from both sides

4x = 81

divide both sides by 4

x= 81/4

i hope that's right
