Answer:
Step-by-step explanation:
y = -2/3 x multiply both sides the first equation by 6
6y = -4x Add 4x to both sides.
6y + 4x = 0
<u>-9y +4x = - 40 </u> Subtract the bottom equation
15y = - 40 Divide by 15
y = -40/15
y = - 2.7
======================
6y = -4x
6*(-2.67) = -4x
-16 = - 4x
x = - 16/-4
x = 4
Answer:10
Step-by-step explanation: 42/4 is 10.5, but don't round because, that wouldn't work for 4 into 42.
Answer:
1.6 minute. 35 mph and 21 mile away. you divide 35÷21
So, firstly, in order for us to know how much is each baseball card pack, we divide 12 dollars by 4 and we get 3. Therefore, each baseball card pack costs $3. So for 21 dollars, he can purchase 7 baseball card packs. 21 divided by 3 is 7. Hope this answers your question. Have a great day!
The number of even positive integers less than a.b, i.e 90, is 45.
<h3>What are Arithmetic operations?</h3>
Arithmetic operations can also be specified by subtract, divide, and multiplying built-in functions.
Given that
a = 7 and b = 13
⇒ ab
Substitute the values of a and b in the above expression,
⇒ (7)(13)
⇒ 91
Since the number of even positive integers is less than
⇒ ab > even positive
⇒ 90 > even positive
since the even number less than a.b i.e. 91 is 90,
Here, 90 is the 45th number in the series of even positive numbers.
Thus, the number of even positive integer less than a.b, i.e 90, is 45
