Answer:
x=1
Step-by-step explanation: x will always be one unless the value of x is given for example, x wouldnt be one if in the question it says x=10 or x=9 or any number other than one
One tenth of 200 is 1/10 x 200 = 200/10 = 20
20 is your answer.
Answer:
1500 students
Step-by-step explanation:
Divide the number of blonde students by the percentage they are of the school.
225/0.15 = 1500
The total number of students in your school is 1500.
Answer:
Now that the values of m (slope) and b (y-intercept) are known, substitute them into y=mx+b . to find the equation of the line.
y=5/4x+9/4
Step-by-step explanation:
Use y=mx+b to calculate the equation of the line, where m represents the slope and b represents the y-intercept.
To calculate the equation of the line, use the y=mx+b format.
Slope is equal to the change in y over the change in x , or rise over run.
m=(change in y)/(change in x)
The change in x
is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m=(y2−y1)/(x2−x1)
Substitute in the values of x and y into the equation to find the slope.
m=1−(6)/−1−(3)
Finding the slope m.
m=5/4
Find the value of b
using the formula for the equation of a line.
b=9/4
First expression:
For the first expression, remember that parenthesis have priority over other operations. Inside the parenthesis we have the sum of three terms (once you read it as 5 + (-3) + 2. Since the sum is commutative and associative, you can perform this operations in any way you like.
The expression in the parenthesis evaluates to 4, so we're left with 16(4), which means we have to mulply 16 by 4, and the answer is 64
Second expression:
Here, you must use the fact that multiplications/divisions have higher priority than sums/subtractions, so we must perform that operation first. The multiplication is three times four, so the answer is 12. The expression becomes, as before, the sum of three terms:
