Answer:
THEY ARE 37 AND 28
Step-by-step explanation:
LET THE NUMBERS BE X AND Y
X = 9 + Y
X - Y = 9 ........1
X + Y = 65 .....2
ADDING 1 AND 2
2X = 74
DIVIDING BY 2
2X/2 = 74/2
X = 37
AND X = 9 + Y
: Y = X - 9
PUTTING X = 37
Y = 37 - 9
Y = 28
Answer:
24.8
Step-by-step explanation:
We will have to use trigonometry here to find the value of x. The first thing we can see is that we need to work out the hypotenuse. We need to chose whether to use Sin, Cos or Tan. We do that by look at the sides .
→ 'x' is the hypotenuse
→ 12 is opposite
→ The adjacent is the side that doesn't have a numerical value to we look for a formula triangle without adjacent in it
Tan = Opposite ÷ Adjacent
Sin = Opposite ÷ Hypotenuse
Cos = Adjacent ÷ Hypotenuse
We can see the Sin formula has no adjacent in it so we use that formula. However we want to work out the hypotenuse so we have to rearrange the sin formula to get hypotenuse as the subject so
Sin = Opposite ÷ Hypotenuse
Hypotenuse = Opposite ÷ Sin
→ Let's substitute in the values
Hypotenuse = 12 ÷ Sin(29)
Hypotenuse = 24.7519841
So the value of x is 24.8 to 1 decimal place
Answer:
A
Step-by-step explanation:
You take the 64 teams, split it in half, and then the exponent is r
Answer:
41
Step-by-step explanation:
x+(x+70)+28=180
x+x+70+28=180
2x+70+28=180
2x+98=180
2x=180-98
2x=82
x=82/2
x=41
We have that
<span>4x -2y =22------> clear variable y
2y=4x-22--------> y=4x/2-22/2---------> y=2x-11-----> equation 1
2x + 4y = 6------> equation 2
substitute equation 1 in equation 2
2x+4*[2x-11]=6-----> 2x+8x-44=6----> 10x=50------> x=5
then
y=2x-11----> y=2*5-11----> y=-1
