Answer:
3.4
Step-by-step explanation:
5t+5/4-1=4t-3/5. cross multiply over the bracket
(5t+5)5=(4t-3)(4-1)
25t + 25 = -16t -4- 12 - 3
Combine the like terms
25t - 16t +4t = -4-12-3-25
13t = - 44
Divide both sides by 13
3.38
3.4 approximately
Answer:
I believe it is 30 toy planes
Hope this helps.
Step-by-step explanation:
toy cars - 2 = 12
toy planes - 5 = 30
total - 7 = 42
What statements are there? (If there are 3 batches, you'd have 1 cup of milk, just FYI).
Answer:
690
Step-by-step explanation:
Let
hayden have "h"
uri have "u"
and
willow have "w"
Hayden & Uri have 1250. we can write:
h + u = 1250
Hayden & Willow have 830, so we can write:
h + w = 830
Uri has 4 times than Willow, so we can write:
u = 4w
Putting 3rd equation in first, we get:
h + u = 1250
h + 4w = 1250
Now, we take 2nd and 4th equation, which are:
h + w = 830
h + 4w = 1250
Multiplying this first one with -1, gives us:
-1 * [h+w=830] = -h - w = -830
Now we add this up with 4th equation. Shown below:
- h - w = - 830
h + 4w = 1250
----------------------
4w - w = 1250 - 830
3w = 420
w = 420/3
w = 140
We know u = 4w, so u = 4 * 140 = 560
u = 560
Also, we know h + w = 830, so
h + 140 = 830
h = 830 - 140
h = 690
Thus Hayden has 690
