Answer:
The answer to your question is: 1 bag of apples cost $6.
Step-by-step explanation:
We need to write an equation:
1 bag of apples + 3 cartons of strawberries = $18
but 1 bag of apples = 1.5 cartons of strawberries
So
1.5 cartons of strawberries + 3 cartons of strawberries = $18
simplify 4.5 cartons of strawberries = 18
1 carton of strawberries = 18/ 4.5 = 4
finally 1 bag of apples = 1.5 (4) = 6
Answer:
Step-by-step explanation:
2 * 3 * 3 * 3
The prime factors of 54 are given as the below listed.
Prime factors = 2 x 3 x 3 x 3
In factorisation and expansion, we can also write it as { 2, 3, 3, 3 }
If it needs to be written in exponential form, we have
Written in exponential form, we get 2^1 * 3³
If it needs to be written in standard form, we have, 5.4 * 10^1 or 54 * 10^
If need be and we are asked to find the expanded form which is
50 tens + 4 units
4x-7y=1 (x,5) Since y is given, plug it in.
4x-7(5)=1 and solve for x.
4x-35=1 Add 35 to each side.
4x=36 Divide each side by 4.
x=9
ANSWER: The solution is (9,5)
Okay so basically, you subtract 18 on both sides since the 18 doesn't work, making the equation
<span>x</span>²<span> - 10x = -18
So then you add (b/2)</span>²<span>, which is 25, to both sides, to get
</span><span>x</span>²<span> - 10x + 25 = 7
</span><span>After this, you factor.
</span><span>(x-5)(x-5) = 7
</span><span>Then you simplify.
(x-5)</span>²<span> = 7
Then you solve for x.
</span>√(<span>x-5)</span>²<span> = </span>√7
x-5 = (+ or -)√7
~ x= 5 (+ or -)√7 ~
Hope this helps!
