It represents the first one 3+(-1)
Answer:
cuz they are chairs
Step-by-step explanation:
Answer is -10
Step by step exploration
7x=-70
x=-70/7
x=-10
The side lengths are given in proportions which are 2:3:5:6. The perimeter is given as the sum of all the sides which is given as 48 cm. Using ratio and proportion, the sum of all the sides or the perimeter is proportional to the sum of all the fractions and the largest fraction is proportional to the longest side of the quadrilateral.
Let x be the longest side of the quadrilateral. The largest proportion is 6.
6/(2+3+5+6) = 6/16
6/16 = x/48
x= 18 cm. The longest side is 18 cm. The other sides are 6, 9, 15 using the other proportions.
Evaluating an expression consists of just replacing the letter by its value and do the calculus.
We have the expression 14b - 513. And by hypothesis, b = 44.
So just replace b by 44.
14b - 513 = 14*44 - 513 = 616 - 513 = 103.
So 14b - 513 = 103 (answer b) when b = 44.
Hope this helps! :)
