(88 + 92 + 96 + x) / 4 = 90
(276 + x) / 4 = 90
276 + x = 90 * 4
276 + x = 360
x = 360 - 276
x = 84 <=== he would need an 84
Answer:
Taht problem equals -77 so I would say d, good luck!
Answer:
y= -2x-6
Step-by-step explanation:
Answer:
1) 5/2
2) c = - 1 /2
Step-by-step explanation:
1) 3^b = 9 root 3
Write in exponential form
write the expression in exponential form with the base of 3
3^b = 3 ^ 5/2
Since the bases are the same , set the exponents eqaul
b = 5/2
Therefore, your answer is 5/2
2) 3 ^ c = 1/√3
Write in exponential form
Write the expression in exponential form with the base of 3
3^c = 3 ^ -1/2
Since the bases are the same , set the exponents equal
c = - 1/2
Therefore, the answer is c = - 1/2
