Not necessarily. You could have done your multiplication wrong. Or in some cases, yes, you could have to use another skill. For example, you can't solve an optimization problem with addition, you need some calculus skills under your belt.

Answer:
64 degrees
Step-by-step explanation:
Lets find the measure of the other angle in the other triangle with measures of 84 and 36.
Since there are 180 degrees in a triangle, we just add the other two angles and subtract from 180:
84 + 36 = 120
180 - 120 = 60
So the measure of the other angle in the other triangle is 60. Since there is a right angle we subtract 60 from 90
90 - 60 = 30
So the triangle with the missing angle has two angles with measures of 86 and 30. Now we add the measures and subtract from 180 again.
86 + 30 = 116
180 - 116 = 64
So the missing angle has a measure of 64 degrees
Answer:
200% of the number she invited.
Step-by-step explanation:
20/10 = 2
2 x 100 = 200
Answer:
3x+5y=105
x+y=25
Step-by-step explanation:
x is the number of 3 mile runs so the total distance travelled is 3x miles. y is the number of 5 mile runs so the total distance travelled is 5y miles. Together Gavin travelled 103 miles so 3x+5y=105.
The number of 3 mile and 5 mile runs he did in total were 25 so x+y=25.
So the answer is:
3x+5y=105
x+y=25
Done.
