Step-by-step explanation:
By pythagoras triplet
sum of square of bigger side should be equal to sum of square of remaining two sides
so 75² + 33² = 5625 + 1089 = 6714
and 89² = 7921
here 6714 is not equal to 7921
so this triangle is not right angled triangle

Yearly budget= $26,760
Fixed expenses per month= $1340
Fixed expenses per year (1340×12) =$16,080
Living expenses per month= $850
Living expenses per year (850×12)= $10,200
Annual expenses= $60
Add ALL the expenses together.
16,080+10,200+60= £26340
Therefore her monthly budget is balanced. Shes not in deficit.

Say for example, you have the improper fraction 18/7
The first step is to find out how many times 7 fits into 18
This looks like flipping the fraction, 7/18 = 2 whole times with 4 parts left over
The 4 left over gets put in front of the original number (7) to give 2 4/7
To check if you have done it correctly, multiply the whole number (2) by the denominator ( 7 ) and then add the numerator.
2 x 7 = 14 + 4 = 18
Hope this helps

PEMDAS
parentheses

multiplication
division
addition
subtraction
do it in that order. but multiplication and division are on the same level so whichever comes firsts gets solved first and addition and subtraction are on the same level so whichever that come first gets solved first
Answer:
x=-1 and y=-5
Step-by-step explanation:
ሰላም!
Given expressions let them given as two equations
- y=2+7x....... equation (1)
- -2x+6y=-28..... equation (2)
Thus, substitute y=2+7x into equation (2)
simplify it
subtract 12 from both sides
divide both sides by 40
Therefore, as we get the value of x=-1 substitute it to equation (1) and solve for variable y
To be more sure make a cross check on both of the two expressions
Thus,
1) y=2+7x .... substitute y=-5 and x=-1 and check if it is equal
-5=2+7(-1)
-5=2-5
-5=-5
2)-2x+6y=-28... substitute and check
-2(-1)+6(-5)=-28
2-30=-28... (-a)(-b)=ab
-28=-28
Hope it helps!
