Answer: 15

Step-by-step explanation: 5+9+11+12+13+14+17=81

Make an equation based on this and solve for the variable (x)

81+x/8=12

12*8=96

81+x=96

96-81=15

x=15

Two angles are supplementary if their sun is 180. The larger angle measures five degrees more than four times the measures of a
Jet001 [13]

Answer:

The smaller angle is 35 and the larger one is 145.

Step-by-step explanation:

In order to find this, we need to express the larger angle in terms of the smaller angle (x).

4x + 5 = large angle.

Now that we have this, we can add them together and set equal to 180.

x + (4x + 5) = 180

5x + 5 = 180

5x = 175

x = 35

Now that we have the value of the smaller angle, we can plug in to get the larger angle.

y = 4x + 5

y = 4(35) + 5

y = 140 + 5

y = 145

kari74 [83]
<span>a) define the variables
The variables are x and y ; x can represent the number of times Aleah goes swimming ; while y can represents the number of times Aleah goes skating.

b) are there any restrictions on the variables? 
The total sum of both activities must be equal or less than $80 a month

c) write a linear inequality to represent this situation
</span><span>Swimming costs $5 each time and skating costs $4 each time. No more than $80 a month.

5x + 4y <u><</u> 80
