Answer:
100
Step-by-step explanation:
4 x (2 + 3)
for this equation u have to use PEMDAS so u have to solve the parenthesis first which is 5 then exponets which is 
which is 25 and 24 x 4 gives you 100
hope this helps, if im wrong sorry
The opposite angles of an inscribe quadrilateral are supplementary.
angle P + angle R = 180
6x + 7 + 12x + 11 = 180
18x + 18 = 180
18x = 162
x = 9
Now we will substitute in the value of x to find angle P and R.
angle P = 6(9)+7 = 61
angle R = 12(9)+11 = 119
Now we will find the value of y.
angle Q + angle S = 180
10y + 7 + 3(3y + 7) = 180
10y + 7 + 9y + 21 = 180
19y + 28 = 180
19y = 152
y = 8
Now substitute in the value of y to find angle Q and S.
angle Q = 10(8)+7 = 87
angle S = 3(3*8+7) = 93
Hope this helps :)
Answer:
x = 1, y = 3
Step-by-step explanation:
Use the y and substitute it into the 2nd equation. Solve for x. Then use that answer to solve for y.
No intervals are showing, but here is how to solve this equation.
0.35x - 4.8 < 5.2 - 0.9x
Add 4.8 to both sides
0.35x < 10 - 0.9x
add 0.9x to both sides
1.25x < 10
divide both sides by 1.25
x < 8
Interval Notation:
If we graphed this on a number line, x goes toward negative infinity.
Answer: (-∞, 8)
Hope this helps! :)
