Answer: 672

1. You need to find the arena of the missing piece so with the 40 on top you will subtract 12 which will give you 28

2. To find the other side subtract 28-12 to get 16 then you will multiple then together to get 448

3. Now just Multiply 40 and 28 to get 1120

4. Subtract 1120 and 448 and you’ll get the answer of 672

Answer:

17 teaspoons

Step-by-step explanation:

1 tbs : 3 tsp

$5 \frac{2}{3} = \frac{17}{3} \\ \frac{17}{3} tbs \: = 3( \frac{17}{3} )tsp \\ \frac{17}{3} tbs = 17tsp$

Always start by converting mixed numbers into fractions;

multiply the whole number part by the denominator (under part) of the fraction part and add this to the numerator (upper part);

Then simply apply the ratio.

Write an equation for a line that is parallel to 2x+5y=15 and passes through the point (-10, 3)

Lyrx [107]

Answer:

The equation of the line is,

$y = - \frac{2}{5} x - 1$

Step-by-step explanation:

First, you have to write it in a form of y = mx + b :

$2x + 5y = 15$

$5y = 15 - 2x$

$y = 3 - \frac{2}{5} x$

$y = - \frac{2}{3} x + 5$

When both lines are parallel to each other, they will have to same gradient value. So the equation of the line is y = (-2/5)x + b. Next, you have to find the value of b by substutituting (-10,3) into the equation :

$y = - \frac{ 2}{5}x + b$

$let \: x = - 10,y = 3$

$3 = - \frac{2}{5} ( - 10) + b$

$3 = 4 + b$

$3 - 4 = b$

$b = - 1$
