Answer:

The length of AB is 19.

Step-by-step explanation:

Lengths BC and AD are congruent to each other.

BC: 17x + 4 equals AD:18x

17x + 4 = 18x .... that's the equation it makes and the equation we are going to solve.

\ 17x + 4 = 18x \\  \frac{ - 17x  \:  \:  \:  \:  \:  \:  \:\: =  - 17x} {4 = 1x}  \\   \\ \frac{4 }{1}  =  \frac{1x}{1} \\ 4 = x

Since we found out the value for 'x', now we are going to plug it in 4x + 3.

4x + 3 \\ 4(4) + 3 \\ 16 + 3 \\ 19

The length of AB is 19.

There were thirteen friends playing a video game online when six players quit.If each player left had eight lives how many lives
Lorico [155]
They had 56 lives in total

Explanation: if there were thirteen friends to begin with and six quit that would leave them with 7 friends. If those seven remaining friends each had 8 lives, you multiply those 7 friends by 8 lives which would get 56.

If all thirteen friends were still in the game then they would have 104 lives all together.

Kristi invests $3,000 at a 7.25% annual simple interest rate, and her sister Kari invests $3,200 at a 6.25% annual simple intere
True [87]

Answer:

Kristi

Step-by-step explanation:

The formula for Simple Interest =

Principal × Rate × Time

For Kristi

Kristi invests $3,000 at a 7.25% annual simple interest rate,

Principal = $3000

Rate = 7.25% = 0.0725

Time = 1

Simple interest = $3000 × 0.0725 × 1

= $217.5

For Kari

Her sister Kari invests $3,200 at a 6.25% annual simple interest rate.

Principal = $3200

Rate = 6.25% = 0.0625

Time = 1

Simple interest = $3200 × 0.0625 × 1

= $200

From the above calculation, we can see that: Kristi will earn the greater amount of interest after one year
