Answer:
the two numbers are 151 and 66
Step-by-step explanation:
x+y =217
x-y = 85
add the two equations
x+y =217
x-y = 85
-------------
2x = 302
divide by 2
2x/2 = 302/2
x = 151
now find y
x+y =217
151+y =217
subtract 151 from each side
y = 217-151
y =66
Answer:
If you are talking about the rectangular prism the equation is
2 × L × W + 2 × L × H + 2 × W × H
If you are talking about Triangular prism the equation is
B × H + L × S + L × B + L × C
The right triangle is also Isosceles. It has two equal angles of 45°.
(hypotenuse)² = 2S²
4 = 2S² => S = √2
Therefore B is the correct answer.
Answer:
circle
Step-by-step explanation:
The equation
x² + y² = r²
Represents a circle centred at the origin with radius r
x² + y² = 25 ← is in this form and
is a circle centre (0, 0) with r = 5
Answer:
a.70. b.50
Step-by-step explanation:
- If Cartie takes $10 from her account for 7 days she would have taken $70 out.
- Next we look at the net problem it is asking us how much is left we already know from the equation above that we need to subtract 70 from 120
- We now have both answers A. being that she would have taken $70 in total out of her account and B. being that she would have $50 left in her account.
