Marcus needs 3 1/10 m of blue fabric and 1 1/5 m of yellow fabric to make his costume. How much more blue fabric than yellow fab

Kamila [148]

Answer:

$1\frac{9}{10}\ m$

Step-by-step explanation:

we know that

To find out how much more blue fabric than yellow fabric does Marcus need, subtract the quantity of yellow fabric from the quantity of blue fabric

step 1

Convert mixed number to an improper fraction

$3\frac{1}{10}\ m=\frac{3*10+1}{10}=\frac{31}{10}\ m$

$1\frac{1}{5}\ m=\frac{1*5+1}{5}=\frac{6}{5}\ m$

step 2

Subtract the numbers

$\frac{31}{10}-\frac{6}{5}=\frac{31}{10}-\frac{12}{10}=\frac{19}{10}\ m$

Convert to mixed number

$\frac{19}{10}\ m=\frac{10}{10}+\frac{9}{10}=1\frac{9}{10}\ m$

Answer:

x = -4 and x = 5

Step-by-step explanation:

Since $x^2 + 2x$ and $3x + 20$ both equal to y, we know that the expressions equal to each other. We can write a new equation base on that.

$x^2 + 2x = 3x + 20$

Now we solve the equation.

$x^2 + 2x = 3x + 20$

$x^2 - x = 20$

$x^2 - x - 20 = 0$

$(x + 4) (x - 5) = 0$

$x + 4 = 0 ; x -5 = 0$

$x = -4 ; x = 5$

Amanda and Ndiba are selling flower bulbs for a school fundraiser. Customers can buy packages of tulip bulbs and bags of daffodi

Mumz [18]

Answer:

daffodil = $13 Tulip = $7

Step-by-step explanation:

6t + 12d = 198

7t + 6d = 127

6t = 198 - 12d

t = 33 -2d

substitute

7(33-2d) + 6d = 127

231 -14d +6d = 127

- 8d = -104

d =13

6t + 12(13) = 198

6t +156 = 198

6t = 42

t = 7
