Answer:
x = -4 , y = 3
Step-by-step explanation:
5x - 7y = -41 ... (i)
-3x - 5y = -3 ... (ii)
Multiplying (i) by -3 and (ii) by 5 ;
-15x + 21y = 123 ... (i)
-15x - 25y = -15 ... (ii)
Subtracting (i) by (ii) ;
0 + 46y = 138
46y = 138
y = 138 ÷ 46 = 3
Returning to equation (ii) ;
-3x - 5(3) = -3
-3x = -3 + 15
-3x = 12
x = -4
Answer:
4
Step-by-step explanation:
P = s+s+s+s
length = 8
8x2=16
24-16=8
8 / 2 = 4
Answer:
-24 x^7
Step-by-step explanation:
(-2x^2)^3 ·3x
(-2x^2) (-2x^2) (-2x^2)*3x
-8 x^6 *3x
-24 x^7
Zoe will need to buy 48 beads.
3 + 1 + 2 = 6.
6 x 8 = 48.
Hope this helps!!!:)
Hello from MrBillDoesMath!
Answer:
88
Discussion:
Angle Q is an inscribed angle so
measure angle Q = 44 =
(1/2) measure of intercepted arc.
In other words,
44 = 1/2 mST => multiply both sides by 2
m ST = 44*2 = 88
which is the second choice
Thank you,
MrB
