Answer:
164
Step-by-step explanation:
You split figures into 2 separate rectangles
one will be 3cm to 22-14=8cm
another one will be 14cm to 10
So, you get separate areas and sum them
8*3=24
14*10=140
24+ 140= 164
It is always possible for the product of a rational number and irrational number to result in a rational value.
7x+1y = 17.00 can be simplified to y = -7x +17
<span>-7x +17 can then be substituted for y in 3x+ 4y =17.50
</span>3x+4(y) = 17.50
3x+ 4(-7x +17) = 17.50
From here you can solve for X
<span>3x + 4(-7x +17) = 17.50
</span>3x -28x + 68 = 17.50
-25x + 68 = 17.50
-68 -68
-25x = -50.50
÷-25 ÷-25
X = 2.02
You can then replace x with 2.02 in the original 7x + 1y = 17.00 to solve for y.
7(x) + 1y = 17.00
7(2.02) + y = 17.00
14.14 + y = 17.00
-14.14 -14.14
y = 2.86
Then substitute 2.02 for x and 2.86 for y in the original 3x+ 4y = 17.50 to check.
3(x) + 4(y) = 17.50
3(2.02) + 4(2.86) = 17.50
6.06 + 11.44 = 17.50
17.50 = 17.50
So
X = 2.02
and
Y = 2.86
or the solution set is (2.02, 2.86)
Hope this helps
I am 100% sure the answer is a.4
Because it was (2,3) then became (8,12)
2*4= 8 and 3*4= 12
The numbers 2 and 3 were multiplied by 4 to get 8 and 12
LP = HE
5x + 6 = 31
Subtract 6 from both sides
5x = 25
Divide both sides by 5
X = 5
