Answer:
Area = 24 cm²
Step-by-step explanation:
Area = 0.5 x (base x height)
Area = 0.5 x (6 x 8)
Area = 0.5 x 48
Area = 24 cm²
Answer:
(-5,-3)
Step-by-step explanation:
In this case to find the solution you could use substitution. This way you can solve without changing the equation over again.
(b - 2) - 3b = 4
b - 2 - 3b = 4
-2b - 2 = 4
-2b = 6
b = -3
Plug back in to find value a
a = (-3) - 2
a = -5
Check your answer before submitting
(-5) - 3(-3) = 4
-5 + 9 = 4
4 = 4
Hope this helps
Answer:
y = -x + 17
Step-by-step explanation:
A(-10,-3)
B(7,14)
C(5,12)
Need line CD perpendicular to AB through C.
Solution:
slope of AB, m1 = (yb-ya) / (xb-xa) = (14- -3) / (7- -10) = 17/17 = 1
Slope of CD, m2 = -1/m1 = -1 / 1 = -1
Line CD through C, using the point slope form
y-yc = m2(x-xc)
y-12 = -1 (x-5)
rearrange
y = -x + 5 + 12
y = -x + 17
Answer:
The number of children's tickets bought was 300 and the number of adult tickets bought was 700
Step-by-step explanation:
Let
x ----> the number of children's tickets bought
y ----> the number of adult tickets bought
we know that
-----> equation A
-----> equation B
Solve the system by substitution
substitute equation A in equation B
solve for x
<em>Find the value of x</em>
therefore
The number of children's tickets bought was 300 and the number of adult tickets bought was 700
