Step-by-step explanation:
step 1. 17/21 - 2/10 = x (in order to subtract you need a common denominator)
step 2. (17/21)(10/10) - (2/10)(21/21) = x
step 3. 170/210 - 42/210 = x
step 4. 128/210 = 64/105 = x
step 5. x = 64/105.
Answer:
4277.6
Step-by-step explanation:
Hello, I can help you with this
Step one
find the profit using a simple rule of three
if
4000 ⇔ 100%
then, how much(x) is 6.94?
x ⇔ 6.94%
the relation is
the profit is 277.6
hence, her balance after one year is the initial amount plus interest earned
balance= 4000+277.6
balance= 4277.6
I hope it helps, Have a great day
Let s = #small notebooks
Let L = #large notebooks
We Can set up two equations from the info given.
s + L = 6 bought 6 notebooks total
8s + 10L = 56 spent $56
Solve equation 1 for one variable.
L = 6-s
Plug 6-s in equation 2 in place of L
and solve for s
8s + 10(6-s) = 56
8s + 60 - 10s = 56
-2s + 60 = 56
-2s = -4
s = (-4)/(-2)
s = 2
We know s+L = 6 and s=2
2+L = 6
L = 4
4 large notebooks and 2 small notebooks
were purchased
you have shown that 2 angles and the corresponding side are congruent. That is what we would write in the UK
In the US i think its ASA?
Hi there,
Since Eric ran 200 m/min for 4 minutes, then 4×200 = 800m
and he walked 80 m/min for 8 minutes, then 8×80 = 640m
and in total he ran 800 + 640 = 1440m
so he still have 1600 - 1440 = 160m left to reach 1600m
Hope this helped :P
