Answers
Answer:
5 (3 c + 4)
Step-by-step explanation:
We factor out the 5, to get 5(3c+4)
We check by distributing the 5, and we get 15c+20 which is correct!
Hope this helps
The expression equivalent to 15c + 20 is 5(3c + 4).
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given expression is 15c + 20.
We have to find an equivalent expression of this using the distributive property.
For three numbers or expressions a, b and c, Distributive property states that,
a (b + c) = ab + ac
In the expression of 15c + 20, write each terms as a multiple of a common factor.
15c = 5 × 3c
20 = 5 × 4
15c + 20 = (5 × 3c) + (5 × 4)
= 5 (3c + 4)
Hence the correct expression which is equivalent to the given expression is 5 (3c + 4).

Any one know how to do this ? 1 through 4
Answers
Answer:
1. U = 54 T = 72
2. M = 76 N = 76
3. F = 134 EF = 18
4. P = 60 Q = 60 R = 60
Step-by-step explanation:
1. the triangle given is an isosceles triangle. this means that the two angles that aren't connected with a congruent side, have the same measures. These angles are also called base angles
in this case, those two angles are S and U
since we know S is 54, U will also be 54
to find the third angle, add all your know angles, then subtract it from 180. We do this because all the angles in a triangle will always add up to 180.
180 - (54 + 54) = 72
U = 54
T = 72
2. In this case M and N are your base angles. We know that the base angles are equal, and that when you add them with L, you should get 180.
we can start by subtracting L from 180 to find the sum of M and N
180 - 28 = 152
now divide this by 2 to find the individual angles:
152 / 2 = 76
so: M = 76 and N = 76
3. For this one, we can do something similar to what we did in question 1 to find F. Just add the base angle, and subtract it from 180 to find the third angle:
180 - (23 + 23) = 134
In isosceles triangles, there are two lines that are congruent, these two lines are the lines that meet at the abnormal angle. In this case, GF and EF are those lines.
so if GF is 18, then EF is also 18
4. This triangle is an equilateral triangle. This means that all sides and angles are congruent. to find the angles, all we have to do is divide 180 by 3, since there are 3 equal angles.
180 / 3 = 60
every angle is 60

When solve an expression, you have to make the expression equals to 0 by moving all the terms to one side :
x² - 3x - 1 = -3x + 3
x² - 3x - 1 + 3x - 3 = 0
x² - 4 = 0
Next, you have to factorize and solve it :
x² - 4 = 0
x² + 2x - 2x - 4 = 0
x(x + 2) - 2(x + 2) = 0
(x + 2)(x - 2) = 0
x + 2 = 0
x = -2
x - 2 = 0
x = 2

One of the students is chosen at random. What is the probability that this student is wearing a watch or a braclet
Answers
Complete question :
At a certain school, 25% of the students wear a watch and 30% wear a bracelet. 60% of the students wear neither a watch nor a bracelet.
a) One of the students is chosen at random. What is the probability that this student is wearing a watch or a bracelet?
b) What is the probability that this student is wearing both a watch and a bracelet?
Answer:
0.40 ; 0.15
Step-by-step explanation:
Let :
w = watch
b = bracelet
P(W) = 0.25
P(B) = 0.3
P(either a watch or a bracelet) = P(WuB)
P(neither a watch nor a bracelet) = 1 - P(WuB)
1 - P(WuB) = 0.6
a.) probability that student is wearing a watch or a bracelet = P(WuB)
P(neither a watch nor a bracelet) = 1 - P(WuB)
0.6 = 1 - P(WnB)
P(WnB) = 1 - 0.6
P(WnB) = 0.4
B.) probability that student is wearing both a watch and a bracelet : P(WnB)
Using the probability relation :
P(WuB) = P(W) + P(B) - P(WnB)
0.4 = 0.25 + 0.30 - P(WnB)
0.4 = 0.55 - P(WnB)
P(WnB) = 0.55 - 0.40
P(WnB) = 0.15

Probability of an event [tex]=\frac{\textrm{Number of favorable outcomes}}{\textrm{Total number of outcomes}}[/tex]
Step-by-step explanation:
According to the classical approach to assigning probability, if an experiment has [tex]n[/tex] simple outcomes, this method would assign a probability of [tex]\frac{1}{n}[/tex] to each outcome. In other words, each outcome is assumed to have an equal probability of occurrence.
