Mathematics
1 answer:
Volgvan2 years ago
4 0

Answer:

4 and 19

Step-by-step explanation:

One number : 4x+3 (this is 3 more than 4 times x)

Another number: x   This is tricky because the main number for comparison is "another number", which is x

Sum of the #s is 23: Means add them and = 23, so

x+(4x+3) = 23

5x+3=23

5x=20

x=4  and the other # is 4x+3, so 4(3)+3=19

Cassie has test grades of 62, 85 and 89 on the first three tests in herpre-algebra class. What are the possible scores she can m
Vsevolod [243]

Explanation:

The test grade for 1st three tests = 62, 85, 89

Let the fourth test score = x

The result we hoping to get is grade B.

Let's find the average of the four test score

\text{Average = }\frac{Su\text{ m of all test score}}{nu\text{mber of test score}}\begin{gathered} s\text{ um of test scores = 62 + 85 + 89 + x} \\ nu\text{mber of test score = 4} \\ \frac{\text{62 + 85 + 89 + x}}{4}=\text{ Average} \end{gathered}\begin{gathered} A\text{ grade B represents atleast 80} \\ \text{Atleast represents }\ge \\ \frac{\text{62 + 85 + 89 + x}}{4}\text{ }\ge\text{ 80} \\ \frac{\text{236 + x}}{4}\text{ }\ge\text{  80} \end{gathered}\begin{gathered} \text{236 + x }\ge\text{ }80(4) \\ \text{236 + x }\ge\text{ }320 \\ \text{subtract }236\text{ from both sides:} \\ 236\text{ - 236 + x }\ge\text{ }320\text{ - 23}6 \\ x\text{ }\ge\text{  84} \end{gathered}

This means Cassie needs to score 84 or more to get a grade of B

Answer:

(x-2)^{2} +(y+6)^{2} =49

Step-by-step explanation:

equation of circle =

(x-h) ^{2} + ( y-k)^{2} = r^{2}

( h , k ) = center of origin

r^{2} = radius

origin = ( 2 , -6 )

radius = 7

(x-2)^2+(y+6)^2=49
