Answer:

\frac{3 \times 4}{5 \times 4} x -  \frac{3 \times 5}{4 \times 5} x =  -  \frac{2 \times 4}{5 \times 4}  - \frac{1 \times 4}{5 \times 4}

\frac{12x - 15x}{20}  =  \frac{ - 8 - 4}{20}

/·20

12x-15x = -8-4

-3x= -12. /·(-1)

3x=12

x=4

Step-by-step explanation:

\frac{3}{5} x -  \frac{3}{4} x =  -  \frac{2}{5}  -  \frac{1}{4}

Answer:

x=88° a=+3 b=4a-3

Step-by-step explanation:

as triangles ADE and BCE are congruent by sss axiom

so correponding angles are equal

i.e<AED = <BEC

and <DAE =90-60

=30°

so

62°+x+30°=180°

therefore x=88°

Paul and Jim work at a t-shirt factory. They pack t-shirts in boxes and send them
Gwar [14]

Answer:

Jim's box hold more t-shirts by 3 cubic feet

Step-by-step explanation:

Jim's box length = 2 feet

Jim's box breadth = 4 feet

Jim's box height = 6 feet

Volume of box =Length \times Breadth \times Height = 2 \times 4 \times 6 = 48 feet^3

Paul's box length = 3 feet

Paul's box breadth =5 feet

Paul's box height = 3 feet

Volume of box =Length \times Breadth \times Height =3 \times 5 \times 3 = 45 feet^3

So,Jim's box hold more t shirts by (48-45 = 3 cubic feet )

So, Option C is true

Jim's box hold more t-shirts by 3 cubic feet
