If x=2y=4z, express

Mathematics
1 answer:
Umnica [9.8K]3 years ago
8 0
x = 4z

2y = 4z

Dividing both sides by two,

y = 2z

OK, part 1.

x+4y+z = 4z + 4(2z) +z = 13z

When z=2 then x+4y+z =13(2)=26

Part 2.

2x+3y+2z= 2(4z) +3(2z) + 2z = 16z

When z=2 then 2x+3y+2z=16(2)=32

Two sides of an isosceles triangle have lengths of 3 and 10. Find the length of the third side.
lora16 [44]

Answer:

The third side must be 10:  {3, 10, 10}; {10, 3, 3} is not possible.

Step-by-step explanation:

Everything depends on our understanding of "isosceles."

This term indicates that two sides of a given triangle are equal.

If two sides of an isosceles triangle have lengths of 3 and 10, then:

Either 1)  Two sides have length 10 and the third side has length 3.  This is certainly possible

or

2)  sides have length 3 and the third side has length 10.  This is NOT possible, since 3 + 3 adds up to 6, which is less than 10.

X/2 is greater than or equal to -4
irga5000 [103]
\frac{x}{2}≥-4

Pretend the greater than or equal to sign is an equal sign, we will substitute it back in later.

x/2 = -4
Multiply both sides by 2 to get x alone
x = -8
Substitute the greater than or equal to sign back in and voila!
x≥-8
