Estimate the sum of 703 + 620

1 answer:

7 0

When you estimate, you round each number, the add.
We round them to
700+620, which is 1320
So our non estimated answer is 1323
But our estimated answer is 1320

Six more than three times a number is less than or equal to 96. d. Five less then half the distance from Jerod’ s home to the ma

ozzi

First statement : Six more than three times a number is less than or equal to 96.

Let us assume number be n.

We can repharse above statement as :

"6 more than 3 times of n is less than or equal to 96".

Therefore, we can write an ineuality as.

3 times of n = 3n

6 more than 3 times of n = 3n+6.

3n+6 ≤ 96.

_____________________________________________________________

Statement 2: Five less then half the distance from Jerod’ s home to the mall is more then 6 miles.

Let us distance from Jerod’ s home to the mall is d.

We can repharse above statement as:

5 less than 1/2 of d is more than 6 miles.

5 less than 1/2 of d = 1/2d -5 .

Therefore, we can write an ineuality as.

12d -5 > 6.

Similar triangles that have a scale ratio other than 1 are not congruent triangles.

The true statement about the proportions of the sides is $\frac{AC}{DF} = \frac 52$

The scale ratio is given as: 5 : 2

And the corresponding sides are given as:

AB and DE.
BC and EF.
CA and FD.

The above highlights mean that,

$\frac{AC}{DF} = \frac{BC}{EF} = \frac{AB}{DE} = \frac 52$

Hence, the true statement is $\frac{AC}{DF} = \frac 52$
