We know that
[ratio of dogs to cats]=[quantity of dogs]/[quantity of cats]
ratio of dogs to cats=3/1
quantity of dogs=12
quantity of cats=?
[quantity of cats]=[quantity of dogs]/[ratio]-------> 12/(3/1)-----> 4
the answer is
there are 4 cats
Answer:
If we multiply two numbers together, we get a product. A product is the same as a multiple.
If we divide two numbers, we get a factor of the number we are dividing. A factor is the same as a divisor.
Knowing this, we can create two equations.
pq = 210 eq1
p/q = 14 eq2
We have a system of equations. If we substitute eq2 into eq1 so the eq1 is in terms of eq1, we obtain
(14q)q = 210
14q2 = 210
Solve for q from this equation.
q2 = 15
Square-root both sides of the equation.
q = √15
Answer:
Z=18.5
Step-by-step explanation:
2(4z - 6 - 6) = 170 - 46
2(4z - 12) = 124 Use distributive property: a(b - c) = ab - ac
8z - 24 = 124 Add 24 to both sides
8z = 148 Divide both sides by 8
To change a fraction to a decimal , you just divide the number on top by the number on the bottom.
So to change 3/11 to a decimal you divide 3 by 11 and you get 0.272727
= 3/11
= 3 ÷ 11
<span>= 0.272727

you can round this to 0.273
