When adding two digit numbers u will be looking at the ones and deciding if they can regroup them for a ten. You might want to equate regrouping with trading a term that you will understand immediately you will begin to add 2 digit numbers by using ten and ones blocks. And the answer is (107)

When you do an addition problem like 77 + 23 you put each number on top of the other in either way you want to put (In addition) so if you reach a number that goes to ten or up to nineteen you will have to add a one to the seven if you end up at 20 you have to add 2 to the 7 but the only, but your case is different, You would have to add four plus three giving you a seven and and 6 plus 4 giving you a 10 so just put the 10 to the 7 giving you 107

Convert the mixed number 7 4/7 to a mixed decimal and round the nearest thousand

RideAnS [48]

Using a calculator, you can find out that $\sf{ \frac{4}{7}\approx 0.571428571 \approx.571$

and so that means $\sf{ 7\frac{4}{7}\approx 7.571428571 \approx 7.571$

so your answer is

$\sf{ 7\frac{4}{7} \approx \huge{\boxed{7.571}}$

3.2 geometry worksheet

alekssr [168]

Answer/Step-by-step explanation:

5. 21x + 4 = 22x - 2 (corresponding angles)

Collect like terms

21x - 22x = -4 - 2

-x = -6

divide both sides by -1

x = 6

6. (x + 72) + (x + 132) = 180 (linear pair)

x + 72 + x + 132 = 180

Add like terms

2x + 204 = 180

2x = 180 - 204

2x = -24

x = -12

7. 90 = 22x + 2 (vertical angles)

90 - 2 = 22x

88 = 22x

Divide both sides by 22

4 = x

x = 4

8. 12x + 10 = 13x + 3 (vertical angles)

Collect like terms

12x - 13x = -10 + 3

-x = -7

Divide both sides by -1

x = 7

9. 17x = 16x + 5 (alternate exterior angles)

17x - 16x = 5

x = 5

✔️17x

Plug in the value of x

17(5) = 85°

10. 21x - 6 = 20x (corresponding angles)

Add like terms

21x - 20x = 6

x = 6

✔️20x

20(6) = 120°

Pleaseeeeeeeeeeeeeee help

We can use Triangle Inequality Theorem, the length of the third side of a triangle must always be between (but not equal to) the sum and the difference of the other two sides.

4.1 - 1.3 < x < 4.1 + 1.3
2.8 < x < 5.7

so, the answer is 2.8 < x < 5.7
