Answer: 3

Step-by-step explanation:

In 5 years, Jumoke will be 16. 16 divided by 2 is 8. Amina will be 8 in 5 years. If we subtract 5 from 8, we see that Amina is 3 currently.

Answer:

6 years old

Step-by-step explanation:

Suppose Amina's age is "a" and Jumoke's age is "j". We know that Jumoke is 11 years older than Amina, so we can say: j = a + 11

In 5 years' time, Jumoke will be twice as old as Amina then. In 5 years, Jumoke will be j + 5 years old, and Amina will be a + 5 years old. Since Jumoke will be twice as old then, the equation is: j + 5 = 2 * (a + 5)

We can substitute a + 11 in for j in the second equation:

(a + 11) + 5 = 2 * (a + 5) = 2a + 10

a + 16 = 2a + 10

a = 6

Thus, Amina's present age is 6 years old.

Hope this helps!

Y = x + 1
y = 2x - 1

basically we r going to sub in one y for another
x + 1 = 2x - 1
1 + 1 = 2x - x
2 = x

now we sub 2 in for x in either of the original equations to find y
y = x + 1
y = 2 + 1
y = 3

so ur solution is (2,3)

Find the values of x,y,z. This diagram is not a scale.
Serjik [45]

Important:
                             The sum of the three angles inside
                              every triangle is always 180°.


First, look at the left triangle alone.
Two of its angles are 46° and 58° .  (46° + 58° ) = 104°
That leaves (180° - 104° ) = 76° degrees for the third angle.
The third angle in that triangle is 'x'. 
                                                         x = 76° .

At the point where 'x' and 'z' come together:
'x' and 'z' are a "linear pair".
Placed side-by-side, they form a straight line.
So (x + z) = 180° .
But  x = 76°.
So z = (180° - 76°).              z = 104° .

Now look at the the skinny triangle on the right alone.
The angle at the top is 13°, and  z = 104°. 
(13° + 104°) = 117° . 
That leaves (180° - 117°) = 63° for the third angle.
'y' is the third angle.
                                                 y = 63° .

-BARSIC- [3]

No. The area of a square/rectangle is length * height, and 4 * 20 is 80m^2. Because Yoshi has a can of paint that can cover 81m^2, and 81m^2 > 80m^2, Yoshi does NOT need to buy more paint.
