Step-by-step explanation:
triangle formula is ½*b*h
so 5*8 is 40
1/2 of 40 is 20cm
1/2means divideby2soitis40/2
Answer:
20
Step-by-step explanation:
5 times 8 divided by 2 is 20, and you have to make sure to divide bc its a triangle
2x+3y=-6
4x+3y = 12
y=77-9
1+3=6
Ir-y = 5
5x+30
Answer:
2x+3y=6
Step-by-step explanation:

Answer:
x = 47
y = 94
Step-by-step explanation:
Givens
Let the larger number = y Note: y must be even. Why is that?
Let the smaller number = x
Equations
x = 1/2 y
x + y = 141
Solution
Substitute x from the first equation into the second equation
1/2 y + y = 141
Change 1/2 y to 0.5y
0.5y + y = 141
Combine the left
1.5y = 141
Divide both sides by 1.5
1.5y/1.5 = 141/1.5
Do the division
y = 94 And y is even.
================
x = 1/2y
x = 1/2*94
x = 47
Check
The smaller number is 1/2 the larger one This is correct.
47 + 94 = 141 and this also checks.
Answer:
x = 47
y = 94
Step-by-step explanation:
We know that one number is half another number and the sum of these two numbers is 141. We are to find the numbers.
Assuming and to be the numbers, we can write it as:
--- (1)
--- (2)
Substituting the value of from (1) into (2) to get:
y = 94
Now substituting this value of in (1):
x = 47
Translating it in other words:
One number is double the other number and the sum of the two number is 141.
