Answer:
3/4=9/12
Step-by-step explanation:
3x3= 9
4x3= 12
The pattern:
So it goes, 1, 2, 3, as the first number in each equation right.
Then it goes 4,5,6 as the second number in each equation.
<span>In other words, the first number + 3 = the second number
</span>
The sum or 3rd number is a zig zag pattern from the first and second numbers as shown below.
1 2 3 4 5 6 <span>7 </span>8 9
4 <span>5 </span>6 7 8 9 10 11 <span>12
</span>
1 * 5 = 5, 2 * 6 = 12, 3 * 7 = 21 .... 8 * 12 = 96
<span>So the answer of </span><span>8+11=96</span>
Answer:
120
Step-by-step explanation:
The sum of the angles is 180 since it forms a straight line
2x+ x+90 = 180
Combine like terms
3x +90=180
Subtract 90 from each side
3x+90-90=180-90
3x= 90
Divide each side by 3
3x/3 = 90/3
x = 30
We want angle DBC = x+90
= 30+90
=120
Answer:
solution: (3, 5)
Step-by-step explanation:
Solve this system of equations
{2x + y = 11
{5x - y = 10
add the equations to use elimination method.
2x + 5x + y - y = 11 + 10;
7x = 21
x = 21/7 = 3
x = 3
y = 11 - 2x = 11 - 2*3 = 11 - 6 = 5
