Answer:
x=4, y=1
Step-by-step explanation:
We can solve this set of equations using elimination.
Multiply the first equation by 3:
Multiply the second equation by 5:
Now we take
Therefore, .
To solve for x, substitute y=1 into the second equation.
Hence, .
If b+2(a+1) = c, find the value of a+1
Subtract b from both sides: b+2(a+1) - b = c - b
2(a+1) = c - b
Divide both sides by 2:
a+1 = (c - b) /2
Answer:
71/44
Step-by-step explanation:
Here the LCD is the product of the two denominators given: 11*8 = 88.
We rewrite 4/11 as 32/88 and 10/8 as 110/88. Now the denominators are the same.
Combine 32/88 and 110/88. We get the sum 142/88, which reduces to 71/44.
Answer:
It is because a rectangle has 4 congruent sides.
A rectangle has 4 congruent sides since it has four 90 degrees sides, its corners. This someone say a shape with 3 congruent sides is a rectangle.
This is why it is wrong.
