tatyana61 [14]4 years ago

Answer:

If the first number is x and y is the second number

x = 11

y = 18

Step-by-step explanation:

If x is the first number and y is the second number then:

x + 7 = y

The sum of the two numbers is expressed as:

x + y = 29

In order to find what the two numbers are, use what you know. According to the first equation, y equals the first number(x) plus 7, so you can substitute that for the y in the second equation

x + y = 29

x + (x + 7) = 29

2x + 7 = 29

2x + 7 - 7 = 29 - 7

2x/2 = 22/2

That means x equals 11

Now that x is known, you can find the value for y. The second number(y) is 7 more than than the first number(x) so that means x + 7 = y

11 + 7 = y

y = 18

A rectangle’s perimeter and its area have the same numerical value. The length of the rectangle is 12 units. What is the width o
horrorfan [7]

Answer:

2.4

Step-by-step explanation:

Let the perimeter and the area = x.

L = 12

P = 2(L + W) = x

P = 2(12 + W) = x

A = LW = x

A = 12W = x

2(12 + W) = 12W

12 + W = 6W

5W = 12

W = 2.4

Answer: 2.4

How many times greater is the volume of the large bowl than the volume of the small bowl
arsen [322]
Answer: it depends on how big each bowl could be. depending on how big the diameter of the bowl is, we can figure out what the radius is, and then we could multiply that by pi squared, which gets you the area of the circle. Then we could figure out how much larger the large bowl is than the smaller bowl with the diameter knowledge that we gained.

So, for example, there was a bowl like this: (|||) (imagine that is a full circle) and that would be... about 9 in. across. imagine the smaller bowl is about 3in. across. then, we could figure out the radius by finding the middle, and expand the middle to the edge of the bowl. then, whatever the radius is, we could multiply that by 8, and get the total diameter of the bowl in inches. with that knowledge, we should be able to know the area of the bowl, by getting the diameter, and multiplying it by pi squared which equals 9.42, and then you multiply that by the radius and the diameter to get the area of the bowl.


that is how you could figure out how much bigger the large bowl is than the smaller bowl.

Akio buys scissors for $3.79, tape for $2.57, and pens for $5.80. The sales tax is 6.25%.
Ganezh [65]

Answer:

$0.76

Step-by-step explanation:

3.79+2.57+5.8=12.16

12.16 x 0.0625=0.76

To solve this, you have to add all the prices together and then convert the percentage into a number so that you can multiply it by the total sales. You end up with 0.76 cents as the taxes for Akio's Purchase.You convert the percentage by moving it backward 2 decimal places.
