One number is 2 more than 3 times another. Their sum is 22. Find the numbers.

1 answer:

8 0

One number is x.
The other number is 2 more than 3 times the first number, so it's 3x+2.
The sum of the numbers is 22.

$x+3x+2=22 \\
4x=22-2 \\
4x=20 \\
x=\frac{20}{4} \\
x=5 \\ \\
3x+2=3 \times 5+2=15+2=17$

The numbers are 5 and 17.

frozen [14]

Answer: 101.69

Step-by-step explanation:

Formula we use to find the z-score :-

$z=\dfrac{x-\mu}{\sigma}$ (1)

Given : $\mu=90$

$\sigma=7$

Daniel's z score : z= 1.67

Let x be the raw score for Daniel's exam grade, then substitute the values of $\mu,\ \sigma\ and \ x$ in (1), we get

$1.67=\dfrac{x-90}{7}\\\\\Rightarrow\ x-90=7\times1.67\\\\\Rightarrow\ x=11.69+90=101.69$

Hence, the raw score for Daniel's exam grade = 101.69
