Calculate the numbers that do have 7 in it.
1 to 10 :1
70 to 79:10
1 to 100:1×9+10=19
700 to 799:100
1 to 999:8×19+100=252

intergers with no 7=999-252=747

A florist has 60 tulips and 72 daffodils. The florist will make bouquets with the same number of tulips and the same number of d
kaheart [24]

Answer: 12

Step-by-step explanation:

Given: A florist has 60 tulips and 72 daffodils.

He wants to make bouquets with the same number of tulips and the same number of daffodils in each using all the flowers.

Then, the greatest number of bouquets the florist can make =  GCD (60,72)

where GCD = Greatest Common Divisor

Prime factorization of 60 and 72 :

60 = 2 x 2 x 3 x 5

72 = 2 x 2 x 2 x 3 x 3

GCD(60,72) = 2 x 2 x 3 = 12

Hence, the greatest number of bouquets the florist can make = 12

The sum of and 7x2 is 10x2
Tems11 [23]

<u><em>Answer:</em></u>

The missing term is 3x²

<u><em>Explanation:</em></u>

Addition and subtraction can only take place between like terms.

<u>For two terms to be like</u>, both the variable and its degree must be the same in both terms

<u>Now, consider the given terms:</u>

First term is 7x² has the variable x with degree 2

The resulting term is 10x² has the variable x with degree 2

This means that the missing term is ax²

We need to get the value of "a"

<u>This is done as follows:</u>

ax² + 7x² = 10x²

x²(a+7) = 10x²

a+7 = 10

a = 10-7

a = 3

Therefore, the missing term is 3x²

Hope this helps :)
