I believe #7 is D) 5.5 x W
516.14mm I think that’s the answer
Answer:
The correct answer is 28.
Step-by-step explanation:
Actually Jada makes problem simpler by adding and subtracting 1
that is
87 ₋ 59 ₋1 ₊ 1
so there would be no effect on our final answer because we have added 1 and also subtracted 1
Now,
87 - 59 -1 + 1
87 - 60 +1 ( ∵ -59 - 1 = -60 )
27 + 1 (∵ 87 - 60 = 27 )
28
so the final answer is 28 .
To do this, you have to plug each x value into the rule.
1.y = 15 - 3×2
y = 15 - 6
y = 9
So the first y value would be 9.
2.y = 15 - 3×3
y = 15 - 9
y = 6
3. y = 15 - 3×4
y = 15-12
y = 3
4. y = 15 - 3×5
y = 15-15
y = 0
Hope this helps!
Answer:
- <em>0.75</em><em> liters of 5% hydrochloric acid solution </em>
- <em>0.25</em><em> liters of 45% hydrochloric acid solution.</em>
Step-by-step explanation:
Let us assume that, x liters of the 5% hydrochloric acid and y liters of the 45% hydrochloric acid solutions are combined.
As Rajan need total of 1 liter of solution, so
i.e
--------------------1
As Rajan needs 5% hydrochloric acid and 45% hydrochloric acid to make a 1 liter batch of 15% hydrochloric acid, hence acid content of the mixture of two acids will be same as of the final one, so

i.e
-------------2
Putting value of x from equation 1 in equation 2,





Putting the value of y in equation 1,

Therefore, Rajan must use 0.75 liters of 5% hydrochloric acid solution and 0.25 liters of 45% hydrochloric acid solution.
