Answer:
Step-by-step explanation:
8/11 is equal to x/20
Cross multiply
8 times 16 and 11 times x
128=11x
Divide
Then you get 11/128
Divide and simplify!!
U varies inversely which means p³ will come as a denominator of the constant k.
Therefore, The equation formed will be:
Answer:
r = 15
Step-by-step explanation:
10(8r + 23) = 1430
Divide both sides by 10.
8r + 23 = 143
Subtract 23 from both sides.
8r = 120
Divide both sides by 8.
r = 15
Because it is greater, larger numbers are on the right of the number line...
I'm going to use the substitution method.
If y = - 3/2 - 7, then:
1/2x + 5 = - 3/2x - 7
Combine like terms:
4/2x = - 12. Mutiply both sides by 2/4 to get x = -12 (2/4)
Simplify to get:
x = - 6.
Plug - 6 back in for x in either equation.
Y = 1/2( - 6) + 5 which becomes Y = - 3 + 5.
X = - 6, Y = 2
