Remember that parentheses come first. Follow PEMDAS
To solve the question, first factorize both fraction,which makes:
2 1/6 - 3 4/9
= 2/6 - 12/9
= 1/3-4/3
= -3/3
= -1
Hope ot helps!
5(8x - 10) - 10x + 25(8x - 10) - 10x + 2
= (40x - 50) - 10x + (200x - 250) - 10x + 2
= 40x - 50 - 10x + 200x - 250 - 10x + 2
= (grouping like terms together)
= 40x - 10x + 200x - 10x - 50 - 250 + 2
= 220x - 298
Answer:
23/2
Step-by-step explanation:
first turn the mixed number into a fraction:
2*10=20
20+3=23
so, we get 23/2
Answer:
151
Step-by-step explanation:
Let x = the smaller integer and y = the larger integer.
We have two conditions:
(1) x + 1 = y
(2) y = 2x - 149 Substitute (1) into (2)
x + 1 = 2x - 149 Add 150 to each side
x + 150 = 2x Subtract x from each side
x = 150 Substitute into (1)
150 +1 = y
y = 151
The larger integer is 151.
<em>Check:
</em>
(1) 150 + 1 = 151
151 = 151
(2) 151 = 2×150 -149
151 = 300 -149
151 = 151
