<h3><u>Solution</u><u> </u><u>:</u><u>-</u><u> </u></h3>

  • When x = 6 and y = 1.

1) 4x + 5y

→ 4*6 + 5*1

→ 24 +5 = 29

2) 2x (20-y)

→ 2*6 (20-1)

→ 12 *19 = 228

3) x ÷ 3 + y

→ 6 ÷ 3 + 1

→ 2 +1 = 3

4) 4y ÷ 2 + (8x + 10)

→ 4*1 ÷ 2 +(8*6+10)

→ 2 + (48+10)

→ 2 + 58

→ 60

5 ) 5. Patty made $34 baby sitting on each of 3 weekends. If she spent $50 on gifts for her family, how much money does she have left?

Money made each weekend = $34

Money made in 3 weekend = $34*3 =$102

Money spent = $50

Therefore ,

→Money left = Money made in 3 weekends - Money spent

→ Money left = $102 - $50 = $52

6.Carlos solved 20-(2x6) + 8 divide 4 = 29. Is this the correct answer? ( In attachment it's written 29 and not 28 .)

Given equation is ,

→ 20 - (2 × 6) + 8 ÷ 4 = 29

Solve inside the brackets ,

→ 20 - 12 + 8 ÷ 4

Perform division ,

→ 20 -12 + 2

Perform addition ,

→ 22 - 12

Perform subtraction,

→ 10

<u>No , he is wrong the answer should have been 10 but he got 29 .</u>

Feliz [49]

Answer:

40 nickles

Step-by-step explanation:

Here is the correct question: Earl went to the store and realize he had 7 more Nickles in his pocket then he thought he had; If all the change in earl’s pocket is nickles, he had $2.35 in his pocket, how many more nickles did he think were in his pocket ?

Given: All Nickles in the Earl´s pocket is $2.35.

Remember, 1 Nickles = $.05

∴ Converting the dollar to nickels

$2.35= \frac{\$ 2.35}{\$ .05} = 47 \ nickels

Earl had total 47 nickels in his pocket.

∴ Earl earlier had nickles = 47-7= 40 \ nickles

∵ we know Earl had realized that he had 7 more nickles in his pocket, which means he already had 40 nickles to make $2.35.
