Answer:
x=30
Step-by-step explanation:
So we know its a supplementary angle which is angles athat add up to 180 degrees since its a straight line.
Make an equation: 60+60+2x=180COmbine like terms
120+2x=180
subtract 120 on both sides
2x=60
x=30
Answer:
y = 28
Step-by-step explanation:
Given that y varies directly as x and inversely as z then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = 4 when x = 2 and z = 7, then
4 = ( multiply both sides by 7 )
28 = 2k ( divide both sides by 2 )
14 = k
y = ← equation of variation
When x = 6 and z = 3 , then
y = = 14 × 2 = 28
Answer:
1) 80+(-20)
2) -13+9
3) -5+(8)
I don't quite know how to explain
Just think about 1) 60 is the new temperature, in order to have an addition problem we're going to have to use negative numbers. Since we had to subtract 20, in order to use addition it would be 80+(-20).
Answer:
x = -1.
Reason.
Look at the two tables.
At what value does f(x) and g(x) have the same output?
It occurs at x=-1
At this value... Both f(x) and g(x) equal = 3.
ANSWER
X= -1.
Let's use an example number. In this case, we'll use... 5! You need to multiply the number of hours by how much you need to pay them and you need to add their fee. If David mows a lawn for 5 hours (5.50 × 5 + 15), then you'll have to pay him $42.50. If Ari mows a lawn for 5 hours (6.25 × 5 + 12), then you'll have to pay her $43.25.
Ari's charge is greater than Davids charge!
