Mathematics
1 answer:
barxatty [35]3 years ago
5 0

Step-by-step explanation:

Let us add x to 2\frac{1}{8} to make 4.

\therefore \: x + 2 \frac{1}{8}  = 4 \\  \\  \therefore \: x + \frac{2 \times 8 + 1}{8}  = 4 \\  \\  \therefore \: x + \frac{16 + 1}{8}  = 4 \\  \\ \therefore \: x + \frac{17}{8}  = 4 \\  \\ \therefore \: x = 4 - \frac{17}{8} \\  \\ \therefore \: x = \frac{4 \times 8 - 17}{8} \\  \\ \therefore \: x = \frac{32- 17}{8} \\  \\ \therefore \: x = \frac{15}{8} \\  \\ \therefore \: x =1 \frac{7}{8} \\  \\  \therefore \:1 \frac{7}{8} \: should \: be \: added \: in \: 2 \frac{1}{8} \: to \: \\  \:  \:  \:  \:  \:  make \:  it \: \: 4.

Madison has a bag of 200 marbles. If twenty-two percent of her marbles are navy blue, 80 marbles are royal blue, 38% are baby bl
liq [111]
To make things easier, pretend she has 100 marbles and halve everything except for the percentages (everything will be doubled later).

If 22% of her marbles are navy, then 22 marbles are navy.
If 40 (half of 80) her marbles are royal blue, then 40% of her marbles are royal blue.
If 38% are baby blue, she has 38 baby blue marbles.

How many cobalt blue marbles does she have? Well, 22+40+38=100

Since we added the percentages, the ratio would be the same whether she has 100 or 200 marbles.

Since the percentages of navy, royal blue, and baby blue added up to 100%, she has no cobalt blue marbles.

How can I solve this math equation?
alukav5142 [94]

Answer:

Graphing

Step-by-step explanation:

1) You can graph this equation by using y=mx+b. You can replace that equation with y=3x-1.

M=3

X=x

B=-1

On a graph you would down 1 since it's negative and make a point. Then you would put a 1 under the 3 to make it a fraction. 3/1. Then you would divide 1 by 3 (1 ÷ 3). Then you would go to the right 0.33 because it's positive, and the up 1. Then you would make a second point.

This would only give you one line which wouldn't give you an intersection.
