Write an equation for each of the following phrases or word problems. Solve for the missing variable. Two times a number is 16.

Two plus a number is 28.

Three is a number divided by 6.

Samuel is y years old. In 10 years, he will be 27. How old is Samuel?

A third of a pizza is 400 calories. How many calories in the whole pizza?

Sanjai had $175 in his bank account before he got paid this week. His current balance is $287. How much did he get paid?

1)

2x = 16

16 ÷ 2 = 8

x = 8

2)

2 + x = 28

28 - 2 = 26

x = 26

3)

3 ÷ 6 = 0.5 (I'm not sure about this one)

4)

27 - 10 = y

27 - 10 = 17

y = 17

5)

1/3 = 400 cal

400 + 400 + 400 = 1, 200

whole pizza = 1,200 calories

6)

$287 - $175 = $112

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
