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
29 times 35 would be 1,015
Circumference of a circle is the distance around the circle. This can be found by using the equation below
2*pi*radius
Our diameter, as shown, is 9cm. Since radius is half of the diameter, our radius is 4.5cm.
Therefore, our circumference is...
2 * pi * 4.5 = 9pi cm total
Answer:
No
Step-by-step explanation:
Start by using the distributive property to simplify 8(1/4x+3/4):
8•1/4x=2x
8•3/4=6
The equation now reads: 2x+6-3=17. Subtract 3 from six and you get 2x+3=17.
You can now proceed to answer this like any two step linear equation.
2x+3=17
-3 -3
2x=14
x=7
7 is the solution to this equation
