I figured this out using each of the supplements one at a time. For calcium, Brand A gives you 5mg per spoon and Brand B gives you 4 mg per spoon. If you need 24 mg of calcium per day, divide 24 by each of those amounts per spoon. If you use Brand A, you need 24/5 = 4.8 (our first x value), and if you use Brand B, you need 24/4 = 6 (our first y value). Let's simplify that to (4, 6). That exists is a ratio of 2:3, so the x and y coordinates would be (2, 3) which is in fact a choice up above. Do the same for the Iron for A and B. 15mg needed/4mg per spoon in A = 3.75 (our second x value) and 15mg needed/6mg per spoon in B = 2.5 (our second y value). Simplify that down as well by rounding to (3, 2) which is also a choice. The last one, vitamins: 16mg needed/7mg per spoon in A = 2.2 (our last x value), and 16mg needed/4mg per spoon in B = 4 (our last y value). That can be rounded and simplified to a ratio of (1, 2) but that is not a choice. So... that's what I have! Hope it helps!
2 times 3 minus 3
because you put it how it says
Answer:
the coefficient of x is 2
Step-by-step explanation:
(3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - (3x - y - z)
Apply the distributive law: - (a - b) = -a + b
Therefore, - (3x - y - z) = -3x + y + z
So (3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - 3x + y + z
Collect like terms: = 3x + 2x - 3x - y - y + y + z - z + z
Combine like terms: = 2x - y + z
Therefore, the coefficient of x is 2
Therefore, the coefficient of x is 2
Angles are measured in degrees, written °. The maximum angle is 360°. This is the angle all the way round a point. Half of this is the angle on a straight line, which is 180°.Lines AB and CD are parallel to one another (hence the » on the lines).
a and d are known as vertically opposite angles. Vertically opposite angles are equal. (b and c, e and h, f and g are also vertically opposite).
g and c are corresponding angles. Corresponding angles are equal. (h and d, f and b, e and a are also corresponding).
d and e are alternate angles. Alternate angles are equal. (c and f are also alternate). Alternate angles form a 'Z' shape and are sometimes called 'Z angles'.
a and b are adjacent angles. Adjacent angles add up to 180 degrees. (d and c, c and a, d and b, f and e, e and g, h and g, h and f are also adjacent).
d and f are interior angles. These add up to 180 degrees (e and c are also interior).
Any two angles that add up to 180 degrees are known as supplementary angles.
Circle equation: (x - h) + (x - k) = r²
(h, k) = center
r = radius
The center is (-7, 4)
To find the radius, take the square root of 49.
√49 = 7
The radius is 7.
Best of Luck!
