What is the value of X

What Is The Value Of X

Answers

Answer 1

Answer:

the answer is 70.

Step-by-step explanation:

Since x and 80 are non-adjacent co-interior angles with respect to ( 2x +10 )

So,

x + 80 = 2x + 10 ( sum of two non-adjacent co-interior angles is equal to the exterior angle of that triangle )

=> 80 - 10 = 2x - x *( switching sides of x and 10 )

=> 70 = x

So, the value of x is 70

Answer 2

x + 80 = 2x + 10 (exterior angle property)

2x -x = 80 -10

x = 70

If a is positive whole number which is greater a/5 or a/8 ?

Answers

Answer:

a/5

Step-by-step explanation:

You can choose a random number for a and see which is greater. For example, you can say a = 40.

That would mean a/5 = 8 and a/8 = 5. Since 8 is greater than 5, a/5 will always be greater.

If a is positive whole number then a/5 is greater than a/8.

To determine whether a/5 or a/8 is greater, we can compare the two fractions when a is a positive whole number.

To compare fractions, we can find a common denominator for both fractions and then compare the numerators.

The least common multiple (LCM) of 5 and 8 is 40. Therefore, we can rewrite the fractions with a common denominator of 40:

a/5 = (8a)/40

a/8 = (5a)/40

Now, we can compare the numerators:

When a is a positive whole number, 8a will always be greater than 5a because multiplying a by a larger number (8) results in a larger value than multiplying a by a smaller number (5).

So a/5 > a/8.

Hence, a/5 will be greater than a/8 for any positive whole number value of a.

Dennis and Ivy share some sweets between them in the ratio 7:4 Dennis got 42 sweets. How many does ivy get

Answers

Answer:

[tex]Ivy = 24[/tex]

Step-by-step explanation:

Given

[tex]Dennis : Ivy = 7 : 4[/tex]

Required

Determine the amount of sweet Ivy gets when Dennis = 42

We have:

[tex]Dennis : Ivy = 7 : 4[/tex] and

[tex]Dennis = 42[/tex]

Substitute 42 for Dennis in [tex]Dennis : Ivy = 7 : 4[/tex]

[tex]42 : Ivy = 7 : 4[/tex]

Convert to fraction

[tex]\frac{42}{Ivy} = \frac{7}{4}[/tex]

Cross Multiply:

[tex]Ivy * 7 = 42 * 4[/tex]

Divide through by 7

[tex]\frac{Ivy * 7}{7} = \frac{42 * 4}{7}[/tex]

[tex]Ivy = \frac{42 * 4}{7}[/tex]

[tex]Ivy = 6* 4[/tex]

[tex]Ivy = 24[/tex]

When a variable is by itself the coefficient is 1

Step-by-step explanation:

The same goes for denominators. If there is a whole number, decimal, or variable without a denominator, you can automatically say that the denominator is 1. Because a number multiplied or divided by 1 stays the same.

You need to find the WPM (words per minute) of each person.

Andre - 208 divided by 4 = 52

Noah - 342 divided by 6 = 57

You now know that Andre types 52 words per minute and Noah types 57 words per minute.

Answer: Noah types faster because he types 57 words per minute while Andre types 52 words per minute.

Answer:Noah types faster.

Step-by-step explanation: For Andre ,You do 208 divide 4 which gives you 52.For Noah, you do 342 divide by 6 which gives you 57.And since Noah  type more words which is 57  while Andre type 52, that means Noah types faster.
