What is the question?
Answer: Ann = 67 Josh = 60 Claire = 30
Step-by-step explanation: You get the equation 5x+7 = 157. You get the equation because for example, Claire = x then josh = 2x and Ann = 2x + 7. You do all the math and boom! You get the answer :)
Answer:
Step-by-step explanation:
The 3 angles must add up to 180. So
6x + 4x + 2x = 180
12x = 180
x = 15
Plug this into all the angles and you have your answers
Yintercepts are where x=0
set to zero to solve
0^2+4y^2=16
4y^2=16
divide 4
y^2=4
sqrt both sides
y=+/-2
xintercept is where y=0
x^2+4(0)^2=16
x^2+0=16
x^2=16
sdqrtboth sides
x=+/-4
yintercepts are (0,2) and (0,-2)
xintercepts are (4,0) and (-4,0)
Answer:
The probability can be written as;
6/18
0.333
33.3%
Step-by-step explanation:
First we find the total number of marbles.
4 + 5 + 6 + 3 = 18
Now write the probability in the form of (favourable outcomes / possible outcomes), or 6/18.
Now let's divide.
6 ÷ 18 = 0.33333333... repeating decimal
0.333 × 100 = 33.33333.....%
We can also round this to 33%
