Answer:

Step-by-step explanation:

3 caterpillars (c) are equal to 21, so we know that c is equal to 7. c + 2 clocks (b) is equal to 19; so we can subtract 7 (c) from both sides to get 2b = 12, meaning that b = 6. In the third equation, we see that a flower (f) plus b plus c is equal to 15. Plugging in our values for b and c we get f + 6 + 7 = 15 which adds to f + 13 = 15, subtract 13 from both sides to see that f = 2. Knowing all of the values, we see that c + f*b = ?. Plug in the values for b, c, and f to get 7 + 2*6. Start with multiplying 2 and 6 together to get 12 and add 7

Anybody help me with this

5 in the millions column is worth 5x1 million, but the 5 in the thousands column is worth 5x1 thousand. The 5 on the far left is worth 1000x the other 5 because 1 million = 1000x1000

Okay this my last one can y'all help

a. The solution is (0,2)

b. The first expression will be easier to substitute as in the first expression the variable y is already isolated on one side of the equation so we can easily put 5x+2 in place of y in equation 2.

Step-by-step explanation:

Given equations are:

$y = 5x+2\ \ \ \ Eqn1\\12.5x+2.5y = 5\ \ \ \ Eqn2$

a. Solution

Putting y = 5x+2 in equation 2

$12.5x+2.5(5x+2) = 5\\12.5x+12.5x+5 = 5\\25x +5 = 5\\25x = 5-5\\25x = 0\\x = 0$

Putting x = 0 in equation 1

$y = 5(0)+2\\= 0+2 = 2$

Hence,

The solution is (0,2)

b: Reason:

The first expression will be easier to substitute as in the first expression the variable y is already isolated on one side of the equation so we can easily put 5x+2 in place of y in equation 2.
