Answer:
x = -3.5
Step-by-step explanation:
-2(5x – 3) = 41
-10x + 6 = 41
-10x + 6 - 6 = 41 - 6
-10x/-10 = 35/-10
x = -3.5
There is 20 students in her class.
Ex.
3/10= size of slice; you can get 3 slices from one pizza.
There are 6 pizzas..... 3x6=18; there will be a remained of 1/10 from each pizza because 3/10 is not an even number. Now u would have (6) 1/10's.... So 1/10+1/10+1/10= 3/10 and 1/10+1/10+1/10=3/10..... That makes two more slices for two more students...... 18+2=20 slices for 20 kids in the class! :-)
Answer:
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = intercept
Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis
change in the value of y = y2 - y1
Change in value of x = x2 -x1
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
The line passes through (2,-1) and (4,5),
y2 = 11
y1 = 5
x2 = 10
x1 = 4
Slope,m = (11 - 5)/(10 - 4) = 6/6 = 1
To determine the intercept, we would substitute x = 4, y = 5 and
m = 1 into
y = mx + c. It becomes
5 = 1 × 4 + c = c + 4
c = 5 - 4 = 1
The equation becomes
y = x + 1
The standard form is represented as
Ax + By + C = 0
y - x - 1 = 0
Multiplying through by - 1, it becomes
x - y + 1 = 0
Answer:
The answer to your question is the letter B. the diameter = 3 ft
Step-by-step explanation:
Data
Circumference = 3π feet
The Circumference is defined as the distance around the edge of a circle.
Formula
Circumference = 2πr
Process
1.- Equal the value of the circumference to the formula
2πr = 3π
2.- Solve for r
r = 3π / 2π
3.- Simplification
r = 3/2 or 1.5 ft
4.- Calculate the diameter
diameter = 2 x radius
diameter = 2(1.5)
= 3 ft
This is a case of counter bore holes. The correct answer is C.
Where:
2 ---- Indicates two holes.
∅1.25 THRU ---- Shows that the holes have a diameter of 1.25 through the material.
Then, there is a counterbore of diameter 2.25 and a depth of 1.00.
