Sam has 6x + 8 dollars saved. Teresa has saved 14x + 32 dollars. Together they have $220 saved. How much money have they each saved individually?

Answers

Sam has saved $62 and Teresa has saved $158

Step-by-step explanation:

given,

dollars saved by Sam = 6x + 8

dollars saved by Teresa = 14x + 32

total money = $220

a/q

money saved by,

sam + Teresa = $220

so,

6x + 8 + 14x + 32 = 220

20x + 40 = 220

20x = 220 - 40 = 180

x = 180/20 = 9

x = 9

now,

money saved by,

Sam = 6x + 8 = 6(9) + 8 = $62

Teresa = 14x + 32 = 14(9) + 32 = $158

therefore,

money individually saved by Sam is $62 and by Teresa $158.

Help? question below

Answers

Answer:

12 shirts

Step-by-step explanation:

First, let x = # of shirts and y = total cost in $. Then create an equation with x and y representing each company. The first company is y = 9.65x + 43 and the second company is y = 8.40x + 58. Since we need to find the # of shirts that would result in the equal total cost, we need to find x when y is equal to the other. Thus here is the setup: 9.65x + 43 = 8.40x + 58, and we would get 1.25x = 15, so x = 12.

First you set up your equations
Company 1–> 9.65x+43
Company 2–> 8.40x+58

Next you set them equal to each other
9.65x+43=8.40x+58
9.65x-8.40x=58-43
1.25x=15/1.25
x=12
When you plug 12 into both equations you’ll get that they both equal 158.8

if you have a bacteria cell that you touch at 9:00 am (so now you have one cell on you) and it multiplies every 20 mins how much will i have on me at 4:00

Answers

That’s 7 hours

It doubles 3 times an hour

It doubles 21 times total starting with 1

At 4:00 you will have 1,048,576 bacteria cells.

Well, 9:00 AM to 4:00 PM would be 7 hours. 7 hours into minutes would be 420. 420 divided by 20 is 21. This means it multiplies 21 times from 9:00 to 4:00. Since it multiplies by 2, than you need to skip count with the pattern multiply by 2 and stop once you have 21 numbers.

1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536, 131072, 262144, 524288, 1048576. That would be 21 numbers.

Answers

B. 8
refer to steps for answer!

Step-by-step explanation:

you just have to put the given values in place of the variable names and then simply calculate.

(-2² + 2²) - 2(-2² - 2²) = (4 + 4) - 2(4 - 4) = 8 - 2×0 = 8

so, B is the right answer.

please remember the correct sequence of operations :

first are brackets.

then exponents.

then multiplications and divisions.

and then (at last) additions and subtractions.

and also please remember : multiplying a negative number with a negative number creates a positive result.

that is of course also true for squaring a negative number, as ² just means that the negative number is multiplied with itself.

now you also know the result of -2³, right ?

as this means -2 is multiplied 3 times by itself. what does that do to the sign ?

-2 × -2 = 4 (positive).

but now we have to multiply a third time

4 × -2 = -8 (because multiplying a positive number with a negative number creates a negative result).

Usually, when Landon makes bird food, he mixes 9 cups of seed with 6 tablespoons of maple syrup. However, today, he is short on ingredients. Describe a recipe that would make a SMALLER batch of bird food but still taste exactly the same.

Answers

Answer:

3 cups of seeds and 2 tablespoons of maple syrup

-OR-

6 cups of seeds and 4 tablespoons of maple syrup

Step-by-step explanation:

As this is a ratio of 9:6: "for every 9 cups of seeds, there is 6 tablespoons of maple syrup"

The original ratio is 3:2 "for every 3 cups of seeds, there is 2 tablespoons of maple syrup"

Using this ratio, we can infer that 3:2 or 6:4 would be a simpler answer for this problem. If there is doubt, it would be better to use 3:2 as it is the smallest ratio.

The ratio of cups of seed to tablespoons of maple syrup is 3:2 therefore these are an example to your question:
6 seed and 4 maple

Yes, he will have 56 in.2 of cardboard left over.

Yes, he will have 128 in.2 of cardboard left over

Answer:

No, he needs 16 inches^2 more cardboard.

Step-by-step explanation:

Take the formula and substitute values into it. 6 * 6^2

Do the exponent first to get 6 * 36, and then complete that to get 216. Since he has 200 inches of cardboard and he would need 216, that means he would need 16 more square inches to make his cube.

No he needs 16 in 2 more cardboard
