Answer:
10 donuts and 10 brownies
Step-by-step explanation:
In this case we must solve the system of equations that do not say in the statement:
at least 20 must be, therefore:
x + y = 20 => x = 20 - y
1.5 * x + 2.5 * y = 40
replacing:
1.5 * (20 - y) + 2.5 * y = 40
30 - 1.5 * y + 2.5 * y = 40
y = 40 - 30
y = 10
now for x:
x = 20 - 10
x = 10
therefore, to be a minimum of 20, they must be 10 donuts and 10 brownies
Answer:
18.8
Step-by-step explanation:
the distance between E and F is 6
the distance between F and G is 5
the distance between E and G is 7.8102
add them all together to get 18.8102
X+7< 5
a number= x
increased= +
by = 7
less than 5 = < 5
Add all parts shared 2+3+7=12
Therefore 1 part is 176,496÷12= $14,708.
This means:
Luc has 2 parts: $14,708×2=$29,416
Deborah has 3 parts: $14,708×3=$44,124
Melanie has 7 parts: $14,708×7=$102,956
To check add all values together. If it makes the total amount, then the share is correct. 29,416+44,124+102,956=$176,496
<span>The answer is B. compound.
An element is composed of only one kind of atom. You cannot separate molecule into simpler substances. For example, hydrogen (H) and oxygen (O) are elements each made of only one atom. Two or more different atoms bonded to one another are a compound. For example, 2 atoms of hydrogen (H) and 1 atom of oxygen are bonded to one another and form water. Thus, water is compound. Mixtures consist of two or more substances that are not chemically combined. Solutions and colloids are mixtures.</span>
