When y=6, then in equation 7y=8x-14 we write 6 instead of y:
7×6=8x-14
42=8x -14
8x-14=42 (now we add 14 to both sides of equation)
8x=56 (now we divide by 8 both sides of equation)
x=7

Answer: x=7

7(6)=8×-14
42=8×-14
42+14=8×
56/8=8×/8
×=7

Step-by-step explanation:

Given

A committee of 3 members is formed using

5 Admin, 34 teachers, and 4 staff

Favorable outcomes are selecting 3 members as Administrators

total members =5+34+4=43

Probability is given by

$\Rightarrow P=\dfrac{\text{Favorable}}{\text{Total}}$

$\Rightarrow P=\dfrac{^5C_3}{^{43}C_3}=\dfrac{10}{43\times 41\times 7}\\\\\Rightarrow P=\dfrac{10}{12,341}=0.000810$

3/4a−16=2/3a+14 PLEASE I NEED THIS QUICK and if you explain the steps that would be geat:) Thank youuuuuuu

Jlenok [28]

Answer:

360

Step-by-step explanation:

3/4a - 16 = 2/3a + 14 ⇒ collect like terms
3/4a - 2/3a = 14 + 16 ⇒ bring the fractions to same denominator
9/12a - 8/12a = 30 ⇒ simplify fraction
1/12a = 30 ⇒ multiply both sides by 12
a = 30*12
a = 360 ⇒ answer

PLEASE ANSWER FAST What is the average of the following two numbers? 5.67 x 10^-21 and 7.24 x 10^-19

adell [148]

Answer: The average of two numbers is $3.64835\times 10^{-19}$ .

Explanation:

The first term is,

$5.67\times10^{-21}$

The second term is,

$7.24\times10^{-19}$

Average formula is,

$Average=\frac{\text{Sum of observations}}{\text{Number of observations}}$

$Average=\frac{5.67\times10^{-21}+7.24\times10^{-19}}{2}$

$Average=\frac{5.67\times 10^{-2}\times10^{-19}+7.24\times10^{-19}}{2}$

$Average=\frac{0.0567\times10^{-19}+7.24\times10^{-19}}{2}$

$Average=\frac{(0.0567+7.24)\times10^{-19}}{2}$

$Average=\frac{(7.2967)\times10^{-19}}{2}$

$Average=3.64835\times10^{-19}$

Therefore, the average of two numbers is $3.64835\times 10^{-19}$ .
