B = 2r - 10
b = 56

56 = 2r - 10
56 + 10 = 2r
66 = 2r
66/2 = r
33 = r  <=== there are 33 rabbits

There are 56 birds. And there are 10 less than twice the number of rabbits

let rabbits = r

2r - 10 = 56

Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. Isolate the r.

add 10 to both sides

2r - 10 (+10) = 56 (+10)

2r = 66

Divide 2 from both sides

2r/2 = 66/2

r = 33

33 is your answer

hope this helps

A researcher claims that 90% of people trust DNA testing. In a survey of 100 people, 91 of them said that they trusted DNA testi
tatuchka [14]

You must know that % is a number out of 100.

Therefore given 91/100 trusted DNA surveying, we know as a percentage this is 91% from the equation below:

(91/100)*100=91

We can conclude that 1%=1 person.

Although the difference is only 1 (91-90=1), the actual proportion of people who trust DNA testing is larger than the 90% by 1%.

PLEASE HELP!! Will give brainliest if you give explanation!
MArishka [77]
The equation in slope-intercept is   y=0.625x+7.    


y = mx + b

where: 
m is the slope of the line 
b is the y-intercept of the line

The slope m of the line through any two points (x1, y1) and (x2, y2) is given by:

The y-intercept b of the line is the value of y at the point where the line crosses the y axis. Since for point (x1, y1) we have y1 = mx1 + b, the y-intercept b can be calculated by:

b = y1 - mx<span>1.    hope that helped</span>

Fast hurry skdifhg did did do fish is​
Amiraneli [1.4K]

Answer:

-\frac{7}{10}

Step-by-step explanation:

Given:

\frac{1}{2}- 1 \frac{1}{5}

Number line is from range -2 to 2 with all increment of ±\frac{2}{10} on both sides.

Step 1: First we will solve the equation we will get;

\frac{1}{2}- 1 \frac{1}{5}\\\\\frac{1}{2}- \frac{6}{5}

Step 2: Now we will try to make the denominator common so we will get;

\frac{1\times 5}{2\times 5}- \frac{6\times 2}{5\times 2}\\\\\frac{5}{10}- \frac{12}{10}

Step 3: Now from the number line when we subtract \frac{12}{10}

from \frac{5}{10} we get number of spaces left are - 7

Hence now it will become:

\frac{5}{10}- \frac{12}{10}\\\\\frac{5 -12}{10}\\\\-\frac{7}{10}

Hence the final Answer is -\frac{7}{10}
