To solve this, you have to substitue 2 for x and 1 for y (x=2 and y=1).

8x (the same thing as 8 times x) equals 16 because 8 times 2 equals 16.

16 - 3 = 13

You now want to add 13 + y. Y = 1, so you are adding 13 + 1, which is 14.

8(2) - 3 + 1 = 14

Evaluate 48 + 24 ÷ 8 − 22
Licemer1 [7]

Answer:

Using PEMDAS, we would first divide 24/8=3. Then, since there is no multiplication or division left, we can finish up with adding and subtracting. So, 48+3-22=29.

So 29 is the answer.

Nonamiya [84]

Answer:

144

Step-by-step explanation:

<u>Data:</u>

<em>Emily's age</em> : 46 years old

<u>Find Colin's age</u>

<em>Colin's age</em>: 11 years older than Emily

                    Emily's age + 11

                    46 + 11 = 57 years old

<u>Find Dan's age</u>

<em>Dan's age</em>: 5 years younger than Emily

                  Emily's age - 5

                  46 - 5 = 41 years old

<u>Find their combined ages</u>

<em>Combined ages</em>: Emily's age + Colin's age + Dan's age

<em>Combined ages </em>= 46 + 57 + 41

Total = 144

Therefore, the total of their combined ages is 144.
