Answer:
Form: 2^7, 2^7 = 128
Step-by-step explanation:
You cannot multiply exponent, you must add the exponents.
4 + 3 = 7.
Keep the base the same.
Then find what 2^7 is.
Multiply:
2 x 2 x 2 x 2 x 2 x 2 x 2.
2 x 2 =
4 x 2 =
8 x 2 =
16 x 2 =
32 x 2 =
64 x 2 =
128.
Answer:
C
Step-by-step explanation:
C is the solution
Answer:
x = 2
Step-by-step explanation:
x/5 + 1 = 11
x/5 = 10
x = 50
3 times 12 then 3 times 20
3 x 12 = 36
3 x 20 = 60
60 + 36 = 96
96 ÷ 8
Answer:
The value of x is 7 and value of y is 45
Step-by-step explanation:
In ΔXYZ
∠X = 50°, ∠Y=30°
To Find ∠Z we will use angle sum property of triangle (Sum of all angles of triangles is 180°)
So,∠X + ∠Y + ∠Z = 180°
So,50°+30°+ ∠Z = 180°
∠Z=180°-80°
∠Z=100°
Now we are given that ΔXYZ ≅ΔFED
So, the corresponding sides are equal and the corresponding angles are equal.
So, ∠Z= ∠D
So, 100=2y+10
100-10=2y
90=2y
45=y
Now XY = EF
So, 9 = 3x-12
21=3x
7=x
Hence The value of x is 7 and value of y is 45
