Answer:
Alright well solve for the variable in one of the equation's. then substitute the result of the other equation
Point form: - 175/51, 1/51
Equation form:
x = - 175/51 y = 1/51 Hope this help's :)
Step-by-step explanation:
Answer:


- Provided : Total sold bakery items : 3028 coffee buns and blueberry buns & 1560 more coffee buns were sold than the blueberry buns.
- To find : Number of coffee buns the bakery sold
- First , Subtract 1560 from 3028 :

We just subtacted the number of more coffee buns from the number of told items sold which means that the number of coffee buns and the number of blueberry buns sold are equal for now. Now divide 1428 by 2 :

Now - Let's get back to the second sentence of the question and add 734 & 1560 :

- Hence , The bakery sold 2294 coffee buns.
- Hope this helps , oneesan! ;)

so, we know the mixture is the sum of both types of coffee, thus x + 20 = y, and 4x + 140 = 5y.
To calculate for the standard deviation given the
probability, we use the formula:
s = sqrt (n p q)
where s is standard deviation, n is number of samples = 11,
p is probability of success = 0.7, q = 1 – p = 0.30
s = sqrt (11 * 0.7 * 0.3)
<span>s = 1.52</span>
Truck speed be x
car travel at x+19
they travel in opposite directions
so the separation is (x+x+19) * no. of hours
1048 = (2x+19)*8
x = ((1048/8) - 19)/2
=56
truck speed is 56 miles per hour
car speed is 56+19 = 75 miles per hour
