Vertical angles are equal...so set ur angles equal to each other and solve for x
5x + 10 = 7x - 12
12 + 10 = 7x - 5x
22 = 2x
22/2 = x
11 = x <==
Answer:
Step-by-step explanation:
The following are the given information:
- The handicapped spot, which is
feet wide and next to the curb. - The other three spots are
feet wide. - There are 4 dividing lines between the spots, and each measures
foot.
The Median D therefore will be a sum of the following:
- The width of the Handicapped Spot
- 3 X The width of the other spots
- 4 X The width of the dividing line
Answer:
A (361)
Step-by-step explanation:
A "perfect square trinomial" has the form
ax^2 + 2ab + b^2. If a happens to be 1, which it is in the given x^2 − 19x + c, then 2(1)(b) = - 19. Solving for b, we get b = -19/2.
Then b^2 in the general "perfect square trinomial" is the same as c: (-19/2)^2, or 90.25, or 90 1/4, or 361/4/
Choosing A (361) makes the given expression a perfect square trinomial.
X% of 4 = x*4/100 = 0.04x
y% of 5 = x*5/100 = 0.05y
x% of 4 + y% of 5 = 0.04x + 0.05y
How you express a number, n, as percentage of 11?: [n/11]*100= 9.10n %
Then make n = 0.04x + 0.05y
9.10n %= 9.10[0.04x + 0.05y] %= (0.3656x + 0.455y)%
.
