Answer:
90 and 8
Step-by-step explanation:
The question is : the sum of two numbers is 98 and their difference is 82 find the two numbers
Let two numbers are x and y.
Sum of two numbers is 98
x+y = 98 ....(1)
The difference of two numbers is 82.
x-y=82....(2)
Adding equation (1) and (2) we get :
x+y+x-y=98+82
2x=180
x=90
Put the value of x in equation (1)
90+y = 98
y = 8
Hence, the two numbers are 90 and 8.
Answer:
68 cm²
Step-by-step explanation:
I don't see what you mean for each figure but here goes nothing!
We can split the figure in 2 rectangles
We find the first rectangle by doing 4 x 12 = 48 cm²
The second rectangle would be 5 x 4 = 20 cm²
Therfore we add them up into 20 + 48 = 68 cm²
Hope This Helps!

Answer:
Equation of the line; y=x+3
Step-by-step explanation:
Graph the line that passes through the points (5,8) and (3,6) and determine the equation of the line.
Equation of a line: y=mx +b
Let's find the slope:
8-6/ 5-3= 2/2 = 1
y=x+b
Substitute the points in.
y= 8
x = 5
8 = 5+b
b= 3
The y-intercept is 3.
y=x+3
Points on the line: (-2,1) (-1,2) (0,3) (1,4) (2,5)
Answer:
50.24 in
Step-by-step explanation:
to find how far it it will go you will need to find the circumference and times it by 2 to find the circumference the formula is 2*pi*radius so you would do 2*3.14*4 and that is 25.12 but since it is 2 revolutions you times 25.12 by 2
