Answer:
x= 3
y= 3
Step-by-step explanation:
Step: Solve−x+y=0 for y:
−x+y=0
−x+y+x=0+x (Add x to both sides)
y=x
Step: Substitute x for y in 4x−3y=3:
4x−3y=3
4x−3x=3
x=3 (Simplify both sides of the equation)
Step: Substitute 3 for x in y=x:
y=x
y=3
Answer:
Step-by-step explanation:
Let's see
The probability of the first card being a spade is 13/52 (as there's 13 spades in the deck.
The probability for the second card is 12/51 (because there's 12 spades left in 51 cards total).
The probability for the third is - you guessed it! - 11/50
so the total probability is:
A more generic solution:
Let's use the binomials to find the solution with combinations:
We need to pick 3 cards out of 13. This can be done in
ways.
And the total number of ways to pick 3 cards out of 52 is:
So the probability is:
Which again brings us to the result computed before.
Answer:
-0.5
Step-by-step explanation:
The maximum number of calories per day that should come from simple sugars is 847.5 calories.
<h3>What number calories should come from simple sugars?</h3><h3 />
A nutritionist recommends that an adult of 175 pounds should not take more than 30% of their daily recommended calories from simple sugars.
This means that the maximum number of calories from simple sugars should be:
= 30% x 2,825
= 847.5 calories

Answer:
x = 15
Step-by-step explanation:
Given
See attachment
Required
Find x
The figure in the attachment is a quadrilateral and the angles in a quadrilateral add up to 360.
So, we have:
90 + 6x + 5+ 10x - 40 + 4x + 5 = 360
Collect like terms
6x + 10x + 4x = 360 - 90 - 5 + 40 - 5
20x = 300
Divide both sides by 20
x = 15
Hence, the value of x is 15
