254.47
Step-by-step explanation:
Answer:
85 degrees
Step-by-step explanation:
So we can see that the two angles form a "c." This c indicates that it is a same side interior angle. Same side interioir angles are equal to 180 degrees. So, set both the expressions to 180.
x+90+x+100=180
2x+190=180
2x=-10
x=-5
Substitute in the value for x
-5+90=85
I hope this helps!
To give you the total cost of the sweater you do:
18.74 × 1.06 = 19.8664
Which will be rounded to $19.87 because the measurement is currency (2 d.p.).
Therefore, you do have enough because $20 > $19.87.
Answer:
Step-by-step explanation:
1) Price of 8 pack of toothbrushes = $ 18.12
Price he paid after using coupon = 18.12 - 3 = $ 15.12
Unit rate = Price he paid ÷ number of toothbrushes
= 15.12 ÷ 8
= $ 1.89
2) 0.5 hours = 30 minutes
Duration of guitar class on Monday = 30 minutes
Duration of guitar class on Tuesday = 1.5 hours = 1 hr 30 min
Duration of guitar class on Thursday = 2 hrs
Total duration = 30 min + 1hr 30 min + 2 hrs
= 4 hrs
Amount paid for 4 hrs = $ 180
Rate per hour = 180 ÷ 4
= $ 45
Answer:
x= -15
w= -55
Step-by-step explanation:
I am assuming that you have to find "x" and "w."
Substitute the equations for w.
4x+5=3x-10
Subtract 3x from both sides of the equation.
x+5= -10
Now, subtract 5 from both sides of the equation.
x= -15
Plug in -15 for x in one of the equations.
w= 4*-15+5= -60+5= -55
