Step-by-step explanation:
10x²+2x-8=0
=>10x²+10x-8x-8=0
=>10x(x+1)-8(x+1)=0
=>(10x-8)(x+1)=0
=>2(5x-4)(x+1)=0
Option B
Answer:
the total weight is 12,483 kilos
Step-by-step explanation:
The computation of the weight is shown below:
Wheat = 134 × 62 = 8308
Coffee = 28 × 50 = 1400
Rice 37 × 75 = 2775
Total weight is
= 8308 + 1400 + 2775
= 12,483 kilos
Hence, the total weight is 12,483 kilos
1/8 of all=mystery
mystery=3
'of' means multiply
therefor
1/8 times all=3
multiply both sides by 8/1 to clear fracion
all=24
Answer: 11
Step-by-step explanation:
2 3/4 × 8 = p/4 × 8/1
Let p be the missing number
Convert the mixed fraction 2 3/4 to proper fraction, multiply 4 x 2, then add 3= 11/4
11/4 × 8 = p/4 ×8
p= 11
