Expression: <span>y÷4−3</span>
When <span><span>y=20</span><span>y=20</span></span>, the value of the expression is 2.
Step-by-step explanation:
the numbers of the yellow and white counters
= 288- 38 = 250.
the ratio of yellow to white = 1:4
so,
the numbers of the yellow counters =
1/(1+4) × 250 =1/5 ×250 = 50
the numbers of the white counters =
4/(1+4) ×250 = 4/5 ×250 = 200
and the numbers of the red counters = 38
Answer:
a right triangle
Step-by-step explanation:
because if you rotate your head, then you can see that the top is at a 90 degree angle
The mean would shift to the left because, simply, the average price of the car would go DOWN.
The discriminant is b<span>²-4ac
We can rewrite x</span>² = 4 to x<span>² + 0x - 4 = 0
So a = 1, b = 0, c = -4
</span>Δ = 0 - 4 * 1 * -4
Δ = 16
The answer is B
