Answer:
C
Step-by-step explanation:
The big triangle and small triangles are similar so their corresponding sides are in proportion.
x/15 = 15/9
x= 15*15/9
x=25
Answer:
System of Equations
Step-by-step explanation:
A system of equations refers to a number of equations with an equal number of variables. We will only look at the case of two linear equations in two unknowns. The bracket on the left indicates that the two equations are intended to be solved simultaneously, but it is not always used.
Given:
3 red dresses
2 white dresses
1 blue dresses
Probability that she will wear the blue dress at her party.
3 + 2 + 1 = 6 total number of outcomes.
There is only 1 blue dress so the number of ways it can happen is only 1.
probability of an event happening = number of ways it can happen / total number of outcomes
Probability = 1/6 or 0.166 or 16.6%
4p-7=13
After the first step which is combining like terms, so add the 3p and the single p together.
Next, the negative 7 turns to a positive when we exterminate it from one half of the equation and add it towards the second part.
4p-7=13
+7. +7
4p=20
Divide both sides by 4 to get the p alone.
4p=20
/4. /4
P=5
That is the answer to the entire equation, again though the first step answer is at the very top, i just felt like solving it for you as well.
