How can you use a quick picture to find 3x2.7

NeTakaya

If you mean like a method to solve it fast here I have 1 solution I usually use;

3x2.7
3x.7=2.1
3x2=6
Then in the question there is 1 number behind the decimal point so the answer should have 1 number behind as well.

Lines

kirill [66]

Answer:

line r: y=-2x-2

line s: -2x+1

lime t: -2x+3

Step-by-step explanation:

every slope must be -2 since that's stated in the question

to find b in y=mx+b, you substitute 0 for x and the y coordinate when x is 0 into the equation (for example for slope r, when x is 0 then y is -2, so -2=-2(0)+b) then solve for b (-2=-2(0)+b is -2=b)

basically, b is the y component when x is 0

Sam runs a lemonade stand. One day he collected $6.55 in nickels and dimes. The number of nickels was 6 more than half the numbe

vampirchik [111]

Answer:

Total number of dimes collected = 50

Step-by-step explanation:

Let the number of dimes collected = d

And the number of nickels collected = n

On day collection in nickels and dimes = $6.55

Since, 1 nickel = $0.05

Therefore, 'n' nickels = 0.05n

And 1 dimes = $0.10

Value of 'd' dimes = $0.10d

Total value of 'n' nickels and 'd' dimes = $(0.05n + 0.10d)

So the equation for the total value will be,

0.05n + 0.10d = 6.55

5n + 10d = 655 --------(1)

Number of nickels was 6 more than half the number of dimes.

n = $\frac{d}{2}$ + 6 ------(2)

By substituting the value 'n' from equation (2) to equation (1)

5( $\frac{d}{2}$ + 6) + 10d = 655

$\frac{5d}{2}$ + 30 + 10d = 655

$\frac{25d}{2}$ = 655 - 30

25d = 625 × 2

d = $\frac{1250}{25}$

d = 50

Therefore, total number of dimes collected = 50
