How many two digit numbers are divisible by either 3 or 5?

2 answers:

8 0

There are 18 that are divisible by 5. 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95

now find which of those are divisible by 3 (divide the numbers by three and if its a whole number that works for example 30 divided by 3 is 10 so thats one)

Can someone help me with this problem

${a }^{2} + {b}^{2} = {c}^{2}$

${1}^{2} + {x}^{2} = {2}^{2}$
${x}^{2} = {2}^{2} - {1}^{2}$
${x}^{2} = 3 \\ \\ x = \sqrt{3}$
$\sqrt{3} = 1.73$

Christopher scored 7 more than two times the questions Mathew scored on the math test. If Christopher scored 87 on the math test

viktelen [127]

Answer:

Step-by-step explanation:

To solve this, we can create an equation that represents this situation. Since Christopher score 7 more than twice what Mathew scored, the equation will be:

C = 2M + 7

(Variables are representative of the first letter of each name)

Seeing as Christopher scored 87, we can put that into the equation and solve for M.

So, the equation will be:

87 = 2M + 7

Subtract 7 from both sides in order to isolate variable M on the right side.

80 = 2M

Now solve for M, which is 40 (divide both sides by 2).
