Hi! :)
So to find the range you just have to subtract the lowest number from the highest number. In this graph, the highest number is 95 and the lowest is 20. All you need to do is 95-20 which equals 75.
Range=75
Hope this helps!
Answer:
a) 25/35
b) 30/42
Step-by-step explanation:
a)
Variable x = denominator if numerator is 25
5/7 = 25/x
5 × x = 7 × 25
5x = 175
x = 35
b)
Variable y = numerator if denominator is 42
5/7 = y/42
5 × 42 = 7 × y
210 = 7y
30 = y
Answer:
(5,-5)
Step-by-step explanation:
Let
x-------------> number of baseballs
y-------------> number of bats
we know that
x+y=100----------------> x=100-y --------------> equation 1
4.5x+20y=822 ------------------------> equation 2
<span>I substitute 1 in 2
</span>4.5*(100-y)+20y=822----------------> 450-4.5y+20y=822-----> 15.5y=372
y=372/15.5-----------> y=24
x+y=100------------> x=100-24---------> 76
the answer is
number of baseballs are 76
number of bats are 24
Just a guess but I think it’s Option A
