Answer:
Numbers are 28 and -15
Step-by-step explanation:
Mark first number X, and second number Y, then:
x-y=43
and
x+y=13
We get system of two equations. Solve it by add both them together:
x-y+x+y=43+13
2x=56
x=28 we get first number
x+y=13
28+y=13
y=13-28
y=-15
Answer:
<u>9.66 x 10⁴ minutes</u>
Step-by-step explanation:

=> <u>9.66 x 10⁴ minutes</u>
Answer:
49π
Step-by-step explanation:
area of circle = πr^2
<em>Handy Tip: cherry pies delicious; apple pies are(R) too(2)! so C = πd and A = πr^2</em>
diameter = 14 cm
radius = 14/2 = 7cm
area of circle = π(7)^2
area of circle = 49π
Hope that helps!
