Answer:
x = 2 and y = 1
Step-by-step explanation:
First, solve for y by substituting the second equation as x into the first equation
-2x - 3y = -7
-2(y + 1) - 3y = -7
Simplify and solve for y
-2y - 2 - 3y = -7
-5y - 2 = -7
-5y = -5
y = 1
Solve for x by plugging in 1 into the second equation
y + 1 = x
1 + 1 = x
2 = x
So, the answer is x = 2 and y = 1
are of a circle=pie r squared. So first find the area using the diameter. half of 3.5 is 1.75. 1.75 squared is 3. 06. 3.14 times 3.06 is 9.61. Now find half of that which is 4.81
Answer:
x = 115.5
Step-by-step explanation:
The measure of the chord- chord angle x is half the sum of the arcs intercepted by the angle and it's vertical angle, that is
x = 
(152 + 79) = 0.5 × 231 = 115.5
Answer:
x>0.5
Step-by-step explanation:
move the -5 over to the 4 but make the negative a positive, then divide everything by 2 ant there you go x>0.5
Answer:
the answer is 12 attendees
Step-by-step explanation:
Let a=the attendees & Let d=the cost
if the budget is $97 and the cost of the gala is represented by the equation d=7a+13, substitute the $97 for d
d=7a+13
97=7a+13
now take subtract 13 from both sides
97-13=7a+13-13
since the 13 cancels out on the right side it'll now read:
84=7a
to get a by itself you now divide 7 from both sides getting a by itself
84/7=7a/7
12=a
so the answer will be 12
