10. 2 consecutive integers....x = smaller one, x + 1 = larger one
      2(x + 1) = 3x - 15
      2x + 2 = 3x - 15
      2 + 15 = 3x - 2x
      17 = x

x + 1 = 17 + 1 = 18
so ur 2 numbers are : 17 and 18
===========================
11. 2 consecutive odd integers....x = smaller one and x + 2 = larger one
      5(x + 2) = 8x + 1
      5x + 10 = 8x + 1
      10 - 1 = 8x - 5x
       9 = 3x
       9/3 = x
       3 = x

x + 2 = 3 + 2= 5
so ur 2 numbers are : 3 and 5
=========================
12. 2 consecutive even integers....x = smaller one.....x + 2 = larger one
      1/2x = x + 2 + 2
      1/2x = x + 4
      1/2x - x = 4
      1/2x - 2/2x = 4
      -1/2x = 4
        x = 4 * -2
        x = -8

x + 2 = -8 + 2 = -6
so ur 2 numbers are : -6 and -8

Alex

Answer:

252 bags of maize

Step-by-step explanation:

From the question, we are told that a farmer harvested maize

In the year 2012 = 144 bags of maize

In the year 2013(following year) the harvest decreased in the ratio 3:4

This means

3:4 = 2013: 2012.

Where number of bags harvested in 2013 = unknown = x

3/4 = x/ 144

Cross multiply 4x = 3 × 144

x = 3 × 144/ 4

× = 108

This means 108 bags of maize was harvested in 2013

The total number of bags harvested is = 108 + 144

= 252 bags of maize.

What is the hypotenuse of an triangle with sides 6 and 8 and angles 30 and 60 degrees?
klemol [59]
Hypotenuse ^2 = base^2 + perpendicular ^2

H^2 = 6^2 + 8^2
H^2 = 36 + 64
H^2 = 100
H = 10

(This is a right angle triangle as 60+30= 90
180-90= 90)
