Show that x=1 is not a solution to 4x+2 2 = 13.​

Answers

Answer 1

Answer:

Replacing x = 1 in the equation above, we have: (4x1) + 22 = 13

=> 5 +22 = 13 => 27 [tex]\neq[/tex] 13

So 27 is not equal to 13 => x=1 is not a solution to 4x+22 = 13.

A shade of purple is made with 4 ounces of red paint, 5 ounces of blue paint, 2 ounces of white paint How many ounces of blue paint are needed to make an 88 ounce batch of paint?

Answers

Answer:

40 ounces.

Step-by-step explanation:

We are going to find this by using ratios.

Given that we have 4 ounces of red paint, 5 ounces of blue paint, and 2 ounces of white paint. The total ounces of paint in a shade of purple is 4 + 5 + 2 = 11.

The fraction of the paint that is blue is thus ounce of blue paint/total ounce of paint = 5/11

So, the number of ounces of blue paint are needed to make an 88 ounce batch of paint is fraction of blue paint × 88 ounces = 5/11 × 88

= 5 × 8

= 40 ounces.

Here is a formula for the amount of water needed to cook rice.

w = 1.5r + 0.5

w is the number of cups of water needed.

r is the number of cups of rice to be cooked.

(a) How many cups of water are needed to cook 7 cups of rice?

(b) How many cups of rice can be cooked with 20 cups of water?

Answers

Step-by-step explanation:

So w =water.

1 cup of water is equal to 1.5 times the volume of rice +0.5

so it'd be (11x1.5) + 0.5 for part A and for part B so you'd need to rearrange the equation which i'm not confident on .

W= (1.5 x11)+0.5

W=17

29=(1.5 x r) + 0.5

28.5=1.5r

19= r

There are 15 animals in a barn. These animals are horses and chickens. There are 44 legs in all. Write a system of equations to determine how many horses and chickens are in the barn.

Answers

Answer:

x=8, y=7

Step-by-step explanation:

Lets keep x as the number of chickens and y as the number of horses.

Since each horse has 4 legs and each chicken has 2 legs we get our first equation to be

2x+4y=44

This is because we need to multiply the number of chickens times 2 to get the number of chicken legs, and same for the horses except 4 because they have 4 legs.

the second equation is

x+y=15

next we can use the substitution method to solve.

First we solve for x

x+y=15

x=15-y

We can substitute this into the first equation

2x+4y=44

2(15-y)+4y=44

30-2y+4y=44

30+2y=44

2y=14

y=7

Now we can substitute this into the original equation, x+y=15 and get the equation x+7=15, x=8

The final answer is x=8, y=7

Yesterday I ran 9.6 miles at an average speed of 0.4 miles per 5 minutes. How long did it take me to run the 96 miles?​

Answers

Answer:

Step-by-step explanation:

This is how we do it in college, I hope I can be of some help.

First, you multiple 9.6 miles with 5 minutes. Then, you divide your answer with 0.4 miles. Next, you cancel the two mile units because of division and then be left with 120 minutes.

9.6 miles x    5 minutes   =  48 miles x minute = 120 minutes

                      0.4 miles          0.4 miles

What is 35% of 220? A. .77 B. 7.7 C. 77 D. 770

Answers

Answer:

77

Step-by-step explanation:

35% of 220 is equivalent to 77.

What is function?

A function is a relation between a dependent and independent variable.

Mathematically, we can write → y = f(x) = ax + b.

Given is to find 35% of 220.

Let 35% of 220 be {x}. Then, we can write -

{x} = 35/100 x 220

{x} = 35/10 x 22

{x} = 35 x 2.2

{x} = 77

Therefore, 35% of 220 is equivalent to 77.

the simple interest on a sum of money for 2 years at 12% per annum is rupees 1380
(i) find the sum of money
(ii) the compound interest on this sum for 1 year payable half-yearly at the same rate. ​

Answers

Answer:

5750

710.7

Step-by-step explanation:

Simple interest = principal. * rate * time

Principal (p) = sum of money

1380 = p * 0.12 * 2

1380 = 0.24p

p = 1380 / 0.24

p = 5750 rupees.

The compound interest :

A = P(1 + r/n)^nt

A = final amount

n = number of compounding times per period

t = period

A = 5750(1 + 0.12/2)^2*1

A = 5750(1 + 0.06)^2

A = 5750(1.06)^2

A = 5750 * 1.1236

A = 6460.7

Hence, compound interest is :

Final amount - principal

6460.7 - 5750

= 710.7 rupees
