Answer:
There are 13 1/2 samples poured from the pitcher
Step-by-step explanation:
1/2 ÷ 6 3/4 = 13.5
Each two digit number has two numbers (duh!). Let's allow the tens digit to be x and the units digit to be y. Tens digit is 3 less than the units digit: x = y-3 Original number is 6 more than 4 times the sum of the digits: 10x+y-6 = 4x + 4y This gives us simultaneous equations!First let's clear the mess: 1. x= y-32. 6x-3y=6 Substitute 1 into 2: 6(y-3) -3y =66y - 18 - 3y = 6
3y = 24y = 8 Our units digit is 8 Substitute y= 8 into 1. x = y - 3x = 5 Our tens digit is 5 Therefore, our number is 58
Answer:
10>-15
Step-by-step explanation:
The given inequality is:
-2<3
The inequality has to be multiplied by -5.
The multiplication is same as multiplying a normal equation with a number. The only difference is that the sign of inequality is changed when it is multiplied with a negative number.
So,
-2(-5) < 3(-5)
10>-15
So the correct answer is the last option ..
