Answer:

y = 1

Step-by-step explanation:

4y - 10 = 1y - 7

add 10 to both sides

4y = 1y + 3

minus 1y from both sides

3y = 3

divide by 3 on both sides to get y by itself.

y = 1

hopefully thats what you were asking!

Vedmedyk [2.9K]

Answer:

The total cost of purchase of Matt and Natalie are $29.41

Step-by-step explanation:

We are given the following in the question:

Cost of clothing without tax = $27.75

Tax percentage = 6%

Amount of tax on clothing =

$=6\%\times 27.75\\\\=\dfrac{6}{100}\times 27.75 \\\\=1.665\approx \$1.66$

Total cost of purchase =

=Total bill without tax + Amount of tax

$=27.75+1.66\\=\$29.41$

Thus, the total cost of purchase of Matt and Natalie are $29.41

Gwar [14]

<h3>Jalen can decide a yellow car in 6 possible ways.</h3>

Step-by-step explanation:

The total number of options in Model = 3

{Compact, Luxury, Sport}

The total number of options in Transmission = 2

{Automatic, Manual }

The total number of options in color = 4

{Red, Blue, Black, Yellow }

The color he has decided is YELLOW.

So, the total number of options in model is 3 and transmission is 2.

⇒ The number of ways that can be decided = 3 x 2 = 6 ways

So Jalen can decide a yellow car in 6 possible ways.

For each problem, explain or show your reasoning, a. 160 is what percentage of 40? b. 40 is 160% of what number? c. What number

grigory [225]

Answer:

A. 160 Out of 40 is 400%./// B. The answer is 25/// C. The answer is 3905%

Step-by-step explanation:

( A ) One step solution:

You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.

So, 160 is 40% of = 160 X 100 = 400

( B ) The same thing as A but the numbers are switched

One step solution:

You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.

So, 40 is 160% of = 40 × 100 = 25

160

( C ) Working out a percentage increase or decrease between two numbers is pretty simple. The resulting number (the second input) is 1602 and what we need to do first is subtract the old number, 40, from it:

1602 - 40 = 1562

Once we've done that we need to divide the result, 1562, by the original number, 40. We do this because we need to compare the difference between the new number and the original:

1562 = 39.05

We now have our answer in decimal format. How do we get this into percentage format? Multiply 39.05 by 100?

39.05 x 100 = 3905%
