Answer:

3.600

Step-by-step explanation:

0.25(x+1.6)+5x=18

Open the bracket first

0.25x+0.72+5x=18

Collect like terms

0.25x+5x=18-0.72

5.25x=18.72

Divide both sides by 5.25

x=3.566~3.600(nearest hundredth)

Answer:

x ≈ 3.2

Step-by-step explanation:

0.45(x + 1.6) + 5x = 18

45/100(x + 16/10) + 5x = 18

¹⁰⁾45x/100 + 720/1000 + ¹⁰⁰⁰⁾5x = ¹⁰⁰⁰⁾18

450x + 720 + 5000x = 18000

5450x = 18000 - 720

5450x = 17280

x = 17280/5450

x = 3.17

x ≈ 3.2

The sum of two consecutive integers is -239 find the two integers

xenn [34]

Answer:

The two consecutive integers are -119 and -120

Step-by-step explanation:

As we know that these two integers are consecutive, that means that they will have a difference of 1. This means that we can find the two integers by adding 1 to the sum of -239 and then dividing it by two

$1-239=-238\\\frac{-238}{2} =-119\\-119-1=-120$

Sam deposits $1,000 into an account that pays 6% simple interest annually. He plans to take the money out after 3.5 years. What

lara31 [8.8K]

Well, the formula for simple interest is

$I=prt$

"I" is interest, "p" is the principal, "r" is the rate, and "t" is the time.

If you substitute the numbers, you get

$I=1,000(0.06)(3.5)$

When you multiply them together, you get

$I=210$

So, the simple interest for 3.5 years is $210.

But, in order to get the total balance, you have to add the interest and the principal together.

$B=1000+210 \\ B=1210$

So, the balance after 3.5 years is $1,210.
