Answer:

12

Step-by-step explanation:

43 + 29 = 72

? = 72 - 60 = 12

therefore, 43 + 29 = 12 + 60

Given:

Two weeks ago, the cost of tickets = $30

Now, the cost of tickets = $39

To find:

The percent increase.

Solution:

We have,

Initial value = $30

New value = $39

Formula for percentage increase is:

[tex]\%\text{increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]

Using this formula, we get

[tex]\%\text{increase}=\dfrac{39-30}{30}\times 100[/tex]

[tex]\%\text{increase}=\dfrac{9}{3}\times 10[/tex]

[tex]\%\text{increase}=3\times 10[/tex]

[tex]\%\text{increase}=30[/tex]

Therefore, the percent increase in the cost of tickets is 30%.

Answer:

9/80

Step-by-step explanation:

1/8 = 10/80

1/10 = 8/80

9/80 is fraction between 1/8 and 1/10

The common fraction which is halfway between 1/8 and 1/10 on a number line is 9/80.

We are given that;

The two numbers 1/8 and 1/10

Now,

A fraction represents a part of a number or any number of equal parts.

To find the common fraction that is halfway between 1/8 and 1/10 on a number line, we need to find the average of the two fractions. To do this, we need to add the fractions and divide the sum by 2. To add the fractions, we need to find a common denominator for them. The least common multiple of 8 and 10 is 40, so we can multiply the first fraction by 5/5 and the second fraction by 4/4 to get equivalent fractions with the same denominator:

1/8 + 1/10 = (1/8)(5/5) + (1/10)(4/4) = 5/40 + 4/40

Now we can add the fractions by adding the numerators and keeping the denominator:

5/40 + 4/40 = (5 + 4)/40 = 9/40

To divide this fraction by 2, we can multiply it by the reciprocal of 2, which is 1/2:

(9/40) / 2 = (9/40) x (1/2) = (9 x 1)/(40 x 2) = 9/80

Therefore, by fraction the answer will be 9/80.

Step-by-step explanation:

8 × 4

4 × 6

then add them together

Answer:

56 un²

Step-by-step explanation:

10 un × 8 un = 80 un²

10 un - 4 un = 6 un

8 un - 4 un = 4 un

6 un × 4 un = 24 un²

80 un² - 24 un² = 56 un²

Answer:

$37500

Step-by-step explanation:

Given data

Width of side walk= 5ft

Lenght= 250ft

Cost per square foot= $30

Hence the area of the side walk= 5*250

                                                     = 1250ft^2

Hence the cost = 30*1250

                            =$37500

Answer:

No

Step-by-step explanation:

I would not agree with Jayna because using the distributive property, you can get:

4(a + 2) = 4(a) + 4(2) = 4a + 8

Jayna did not get the right answer because she did not distribute the 4 to the 2 in a + 2 and she only multiplied a by 4.
