Answer:

Hulian's age is 7.

Thomas's age is 22.

Step-by-step explanation:

Let Hulian = h

Let Thomas = t

Set the system of equation:

h = t - 15

h + t = 29

Plug in t - 15 for h in the second equation:

(t - 15) + t = 29

Simplify. Combine like terms:

2t - 15 = 29

Isolate the variable, t. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, add 15 to both sides:

2t - 15 (+15) = 29 (+15)

2t = 44

Divide 2 from both sides:

(2t)/2 = (44)2

t = 44/2

t = 22

Plug in 22 for t in one of the equations:

h = t - 15

h = 22 - 15

h = 7

Hulian's age is 7.

Thomas's age is 22.

If there is an 8% tax on 1.00 item what is the total amount of the transaction

rosijanka [135]

$1.08
you would multiply your cost (1.00) by 8% which is equivalent to .08 and then add to to the original cost. or to skip the middle step just multiply it by 1.08 since you are adding the 8% to 100% of the original cost

In a recent year there were about 400,000,000 mobile internet users. That same year, there were about 1.2 x 10^9 desktop interne

Naddika [18.5K]

Answer:

The number of desktop internet users are 3 times more than the number of mobile internet users.

Step-by-step explanation:

We are given the following in the question:

Number of mobile internet users = 400,000,000

$400,000,000 = 4\times 10^{8}$

Number of desktop internet user =

$1.2 \times 10^9$

Comparison of values:

$=\dfrac{\text{Number of desktop internet user}}{\text{Number of mobile interet user}}\\\\=\dfrac{1.2\times 10^9}{4\times 10^8}\\\\=0.3\times 10\\=3$

Thus, the number of desktop internet users are 3 times more than the number of mobile internet users.

ANSWER SUPER QUICK

Answer: The required equation is $x=(7\times12-34.5)\div8\frac{1}{4}$

Maria can cut 6 sections from the remaining rope.

Step-by-step explanation:

The total length of rope = 7 feet

since 1 feet = 12 inches

Therefore, 7 feet= $7\times 12=84\ inches$

Let x be the number of sections.

Since the instructions are to use 34.5 inches of rope to tie a tarp on top the the tent. Then, the remaining rope should be cut 8 1/4 inch sections to tie tent to stakes in the ground.

then the required equation will be

$x=(7\times12-34.5)\div8\frac{1}{4}\\\Rightarrow\ x=(84-34.5)\div \frac{33}{4}\\\Rightarrow\ x=49.5\div8.25\\\Rightarrow\ x=6$

So, maria can cut 6 sections.

5x-6y=22 in slope intercept

puteri [66]

Slope intercept form means that you have to solve for y.
Subtract 5x from both sides
5x - 6y - 5x = 22 - 5x
= -6y = 22 - 5x
Then divide by -6
-6y/-6 = 22/-6 - 5x/-6
= y = -22/6 + 5x/6
You can reduce the fraction -22/6 to -11/3
y = -11/3 + 5x/6
Then swap the order of your terms so it looks nicer and you don't have a negative in front
y = 5x/6 - 11/3
