Answer:
the answer is -7 3/4
Step-by-step explanation:
7.75/7.5=0.25
it is 0.25 farther from 0 than 7 1/2
Answer:
The value of <em>y</em> = 40.
Step-by-step explanation:
We have been given that Δ ABC is isosceles with AB = AC.
Since opposite angles of equal sides are equal, we have,
∠C = ∠B and so
5<em>x</em> = 40
<em>x</em> = 8
Now, by angle sum property,
∠A + ∠B + ∠C = 180⁰
(2<em>y</em> + 20) + 40 + 40 = 180
(2<em>y</em> + 20) + 80 = 180
(2<em>y</em> + 20) = 180 - 80
2<em>y</em> + 20 = 100
2<em>y</em> = 100 - 20 = 80
<em>y</em> = 40
Hence, the value of y = 40°.
Answer:
-4x + 4
Step-by-step explanation:
4x - 2( 4x - 2 )
→ Expand out 2 ( 4x - 2 )
2 ( 4x - 2 ) = 8x - 4
→ Substitute the expanded bracket back into the expression
4x - (8x - 4)
→ Collect the 'x' values
-4x + 4
1 st you do distributetive property so 4 times x is 4x and 4 times 3 is 12 then you distribute the other side so 2 times 6 is 12 and 2 times 2x is 4x
So now u have the equations 4x + 12 = 12 + 4x and now u can tell that they are equal to each other by using communative property
