Assuming 2x2 is 2 multiplied by 2, and not a variable..

1. Multiply 2 and 2.

4 - 2x +7

2. Add 7 to 4.

11 - 2x.

Since the answer can no longer be simplified, 11 - 2x is your final answer.

Three-eighths of the sum of sixteen times a number and twenty-four. How do you set this up?

patriot [66]

If you break it up:

Three-eighths = 3/8

Sixteen times a number, we'll call the unknown number X, so 16X.

Twenty Four = 24

The sum of 16X and 24 = 16X + 24

We want 3/8 of that sum so we put the sum in parenthesis and we get:

Y = 3/8(16X + 24) where Y is the answer youd get if you knew what X was.

At a candy store you can pay $16.10 for 7 giant lollipop what would be the cost for 6 lollipops?

Alex Ar [27]

Answer: $13.80 for 6 giant lollipops

Step-by-step explanation: To find the cost of 6 giant lollipops at the candy store, we first need to find the unit price for a giant lollipop.

Unit price means the cost per unit,

in this case, the cost per giant lollipop.

Since we know that it costs $16.10 for 7 giant lollipops, to find the cost

for 1 giant lollipop, we need to 16.10 by 7.

16.10 divided by 7 is 2.3.

This means that each lollipop is $2.30.

Now to find the cost for 6, we multiply

the cost per 1 lollipop by 6.

So we have 2.30 × 6 which is $13.80.

So the cost for 6 lollipops at the candy store is $13.80.

Monica and Lauren know that they will need a lot of money in order to make the purchases necessary for a successful bakery. They

xxTIMURxx [149]

Based on the model, the total amount of money in the joined account after the 5 weeks is $767.30

<h3>What are linear equations</h3>

Linear equations are equations that have constant rates

A linear equation is represented as:

y = mx+ b

In this case,

m represents the deposit per week
b represents the initial deposit

So, the linear equations are:

y =153.46x --- for Monica
y = 128.90+ 127.68x -- For Lauren

To calculate the number of weeks, when they have the same amount, we equate both equations

$153.46x = 128.90 + 127.68x$

Collect like terms

$153.46x -127.68x= 128.90$

$25.78x= 128.90$

Solve for x

$x= 5$

Substitute 5 for x in

$y = 153.46x$

$y = 153.46 * 5$

$y = 767.30$

Hence, it will take 5 weeks for both accounts to have the same amount of $767.30
