Number 1 please and number 5 i know that y =x is the starter for number 5 but I don’t know can someone help me please!? :)

1) rate = 175 miles/4 hours, unit rate = 43 3/4 miles/hour

5) y = 2x + 2

Also I think you made a mistake for #2, read explanation please.

Step-by-step explanation:

1) 175 / 4 = 43 3/4 miles/hour.

5) y = 2x + 2, We know that 2 is added since 0 x 2 =/= 2.

2) (Referring to 12^0) When you raise a number to the power of 0 the result is always 1, but if it's negative then the result would be -1 instead.

Expanded form and standard form are both 1, since the base 12 is positive.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
