Answer:
1. 11
2. 17
3. 10
4. 9.1
5. 13
Step-by-step explanation:
1. 2(4)+3
8+3=11
2.-5(-2)+7
10+7=17
3. 1.5(9)-3.5
13.5- 3.5 =10
4.0.3(-2)+9.7
-.6+9.7= 9.1
5. -3/4(-4)+10
3+10=13
Solution:
The interior angles of a triangle sum up to 180°
<u>This means that...</u>
<u>Simplify the distributive property.</u>
<u>Combine like terms.</u>
- 3x + (6 + 52 + 35) = 180
- => 3x + (93) = 180
<u>Subtract 93 both sides.</u>
- 3x + (93) = 180
- => 3x + 93 - 93 = 180 - 93
<u>Simplify both sides.</u>
<u>Divide 3 both sides.</u>
- => 3x/3 = 87/3
- => x = 87/3 = 29
Answer:
9/10
Step-by-step explanation:
Answer:
The value of <em>x</em> is 
.
Step-by-step explanation:
The distributive property is:
a (b + c) = a · b + a · c
The expression is:
Solve using the distributive property as follows:
Thus, the value of <em>x</em> is .
Answer:
Variability is when there is no consistency.
Step-by-step explanation:
Variation in data can be due to various factors. Variability can also be called the spread of data.
Standard deviation is a measure of variability as standard deviation measures the spread of data.
