Answer:
x=12
Step-by-step explanation:
we know that the sum of the angles in a triangle is 180 degrees
to find x we have to calculate the sum of the angles
(10x-11)+(3x-2)+(3x+1)=180
10x-11+3x-2+3x+1=180
16x-12=180
16x=180+12
16x=192
x=192/16=12
If you mean: (4-2)-(3*4) then it is -10
Answer:
Step-by-step explanation:
1. Given that: y = (5 x 9) + (1 x 9)
= 45 + 9
= 54
Using repeated reasoning;
y = (5 x 9) + (1 x 9)
factoring 9 in the equation, we have;
y = 9 (5 + 1)
= 9 (6)
= 54
2i. 7 x 6 = (5 x 6) + (2 x 6)
= (5 + 2)6
= 7 x 6
= 42
ii. 7 x 9 = (5 x 9) + (2 x 9)
= (5 + 2)9
= 7 x 9
= 63
iii. 7 x 7 = (5 x 7) + (2 x 7)
= (5 + 2)7
= 7 x 7
= 49
Therefore, the factors that Pam used repeatedly are 5 and 2.
3. 7 x 8 = (LX) + (LX)
= X(L + L)
Representing L and X by a number,
7 x 8 = (4 x 7) + (4 x 7)
= 7(4 + 4)
= 7(8)
= 7 x 8
= 56
Thus, the generalization is true.
1. y=4x
2. (I am not able to graph it, but here are some points on the line.)
(0,3) (3,6) (5,8) those three should get you to graph a line. When you have these types of problems, make a table. plug in random numbers, that are reasonable, usually 1-6, and plug them into the equation and enter your new y values, then graph the ordered pairs and connect them.
