For this question you can say:

16g - 48g = -32g

and 32h - 40h = -8h

so you will have:

-32g - 8h and you can factor -8 so you will have:

-8(4g + h) :)))

i hope this is helpful

have a nice day

16g - 48g = -32g

and 32h - 40h = -8h

so you will have:

-32g - 8h and you can factor -8 so you will have:

-8(4g + h) :)))

i hope this is helpful

have a nice day

Question

Find the value of sin2a, if tana=-12/5 in the fourth quadrant

Solution 1

Recall the following identities:

from which we get

Since is in the fourth quadrant we know that should be positive, so when we take the square root here, we should take the positive root.

Now recall that

and since is in the fourth quadrant, we expect to be negative. So,

One final identity:

from which we get

Question

the weight of a nickel is 80% of the weight of a quarter.if a nickel weighs 5grams how much does a quarter weigh?

Solution 1

Just divide 100% by 80% and multiply that answer by 5. I'm pretty sure that's how you do it.

Question

The Mulraney's home has 2,550 square feet of living space. A contractor is building an addition to their home that will increase the square footage by 8%. What will be the square footage of their home with the addition?

Solution 1

First we have to find out how much the Mulraney's square footage increases with the addition. To do this, we should multiply the percent of expansion, 8% (0.08) by their current square footage (2, 550)

0.08 * 2,550 = 204

This means that the addition is adding 204 square feet to the Mulraney's house.

To find the total number of square footage, we just add the original (2,550 feet) to the addition (204).

2,550 + 204 = 2754

Therefore,**the square footage of the Mulraney's home with the addition is 2754 square feet.**

0.08 * 2,550 = 204

This means that the addition is adding 204 square feet to the Mulraney's house.

To find the total number of square footage, we just add the original (2,550 feet) to the addition (204).

2,550 + 204 = 2754

Therefore,

You have to find x then add 13

You have to find x then add 13

Question

The product of two numbers is 24 negative if one of the factor is -6 what is the other factors

Solution 1

The other factor is 4 because if you multiply a negative with a positive, you'll get a negative. -6 * 4 will give you - 24.

Question

Find the product of two numbers whose sum is 11 and difference is 3.

Solution 1

The **two numbers** are **7 **and **4**

Let the first number = x

let the second number = y

The sum of the numbers is 11, in algebra form x + y = 11

The difference of the two numbers is 3, in algebra form, x - y = 3

To obtain the two **unknown numbers**, we solve the two equations;

from the first equation, x = 11 - y

substitute the value of x into the last equation;

(11 - y) - y = 3

11 - y - y = 3

11 - 2y = 3

2y = 11 - 3

2y = 8

y = 4

The value of x = 11 - 4 = 7

Thus, the **two numbers** are **7 **and **4**

Solution 2

All you would do is minus what you have, like 11-3= 8 which would be 8+3=11 and 11-8=3 which means now you have the sum of 11 and the difference of 3.

Question

Runyon Company sells T-shirts ($5) and shorts ($6). If total sales were $1,040 and people bought 4 times as many T-shirts as shorts, what was the total number of T-shirts and shorts sold

Solution 1

You answer would be **4,160 **and you get the answer by multiplying 1,040 and 4 and you get **4,160**

Question

during a flu epidemic,146 students out of 680 who attend Lincoln middle school were absent. what percent were absent?

Solution 1

21% were absent, if you divide 146 by 680 and multiply by 100, then round to the nearest whole number, you get 21

Question

Lara solved an equation incorrectly, as shown below: Step 1: 2x = 18
Step 2: x = 18 − 2
Step 3: x = 16
Which statement best explains why Step 2 is incorrect in Lara's solution?
A) She did not divide 18 by 2.
B)She did not add 2 to 18.
C)She did not multiply 18 by 2.
D) She did not multiply 18 two times.

Solution 1

We have been given the steps to solve the equation as

Step 1: 2x = 18

Step 2: x = 18 − 2

Step 3: x = 16

There is an error in step 2.

We have

x is in multiplication with 2. So in order to get rid of 2 from the left hand side, we perform opposite operation of multiplication i.e. division.

So we must divide both sides by 2.

**Therefore, A is the correct option.**

**A) She did not divide 18 by 2.**

Solution 2

The answer is b. 18/2=9
