I NEED THE VALUE OF X

Answers

Answer 1

Answer:

x=18

Step-by-step explanation:

Since the angle is 90, noted by the right angle symbol, we can say that 5x=90

Now we simplify each side.

5x/5 = 90/5

x=18

the value of y is directly proportional to the value of x. If y= 35 when x=140, what is the value of y when x=70?​

Answers

Answer:

17.5

Step-by-step explanation:

first you need to find the relationship between the y and x.

140/35= 4

so then we know that X is four times larger than y

When a quantity is increased or
decreased, what PERCENT describes the
original or starting value?

Answers

Answer:

100%

Step-by-step explanation:

The percentage that describes the original value we are calculating from is 100%

This represents the original value that we are working with.

For example if we are to decrease by 10%, it means we are to be left with 90%

If also we are to increase by 10%, it means that we are to be left with 110%

Give the vertex of each function or inequality
f(x)=|x-1|-1

Answers

Answer:

(1,-1)

Step-by-step explanation:

The vertex is the minimum point (in this case). That happens when x - 1 = 0. The reason for that is because the absolute value is going to added to minus 1. The absolute value is always plus.

x - 1 = 0

x - 1+1 = 0 + 1

x = 1

So the minimum point is going to be (1,-1)

Johnathan went shopping at HEB. He began to look at two different cereals below Sunshine Cornflakes: 24-ounce box for $4.32 Bright Start Cornflakes: 36-ounce box for $5.76 How much less does it cost per ounce?

Answers

Answer:

Step-by-step explanation:

Given that:

Johnathan looked at two different portions of cereals at the supermarket.

They are:

Sunshine Cornflakes: 24-ounce box for $4.32

Bright Start Cornflakes: 36-ounce box for $5.76

To calculate the cost of one ounce of Sunshine cornflakes, we have:

24-ounce box for $4.32

1 - ounce box  will be x

x = ($4.32 × 1 ounce box) / 24 ounce box

x = $0.18

1 - ounce box  will be = $0.18

To calculate the cost of one ounce of Bright star cornflakes, we have:

36-ounce box for $5.76

1 - ounce box will be = ( $5.76 × 1 ounce box) / 36 ounce box

1 - ounce box will be = $0.16

Since 1 - ounce box of Bright star cornflakes is lesser than 1 - ounce box of Sunshine Cornflakes.

Then,  Bright star cornflakes costs ($0.18 - $0.16) = $0.02 per ounce box lesser than Sunshine Cornflakes.

Thus, Bright star cornflakes will be a better buy.

If 2c - 5 = 3d + 4, what does c equal, in terms of d?

Answers

Answer:

D. [tex]\frac{3d+9}{2}[/tex]

Step-by-step explanation:

2c - 5 = 3d + 4

Isolate 2c.

2c = 3d + 4 + 5

Simplify.

2c = 3d + 9

(2c ÷ 2 = c) Find c.

c = [tex]\frac{3d+9}{2}[/tex]

Answer:

[tex]d. \: \frac{3d + 9}{2} [/tex]

Step-by-step explanation:

Follow the steps below.

[tex]2c - 5 = 3d + 4 \\ 2c = 3d + 9 \\ c = \frac{3}{2} d + \frac{9}{2} \: or \: c = \frac{3d + 9}{2} [/tex]

So D is correct.

Kisha saved $12.00 when buying a coat. The coat was on sale for 30% off. What was the original price of the coat?

Answers

Answer:

$40

Step-by-step explanation:

As per linear equation, the original price of the coat is $40.

What is a linear equation?

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. When this equation is graphed, it always results in a straight line."

Given, Kisha got the discount of $12.00 while buying the coat.

The coat was on sale for 30% off.

Let, the original price of the coat was $x.

Therefore, the price Kisha saved while buying the coat was:

$(x ×0.3)

= $0.3x

Now, 0.3x = 12.00

⇒ x = (12.00 / 0.3)

⇒ x = 40

Therefore, the original price of Kisha's coat was $40.
