Whats 70-3x6+9 I need the answer plz

70-3·6+9

Remember PEMDAS.

You must multiply the 3 and 6 together, and you would get 18.

Then, you subtract 18 from 70, which would give you 52.

And finally, you would add 9 to 52, getting 61 as your final answer.

A box has four cards numbered 1 to 3 and four Hong will toss a coin wants and record the toss as heads or tails then he will ran

Papessa [141]

Answer:

Sample Space = {H1, H2, H3, Hfour, T1, T2, T3, Tfour}

O(Card 3 Chosen) = {H3, T3}

Step-by-step explanation:

A sample space is the set containing all the possible outcomes or results that can occur during an event. In this case the sample space will contain 8 outcomes, and it will be as follows:

Sample Space = {H1, H2, H3, Hfour, T1, T2, T3, Tfour}

Now, it is clear from the sample space that there are total two outcomes in sample space, in which the card numbered 3 is chosen. They are:

O(Card 3 Chosen) = {H3, T3}

where, O represents Outcomes.

The sides of a triangle are 5, 12, and n. Write an inequality that expresses the interval of values that n may have.

Airida [17]

Since the sum of third side of a triangle is smaller than the sum of other two sides
So n<12+5
n<17

1. y > 2x + 3 graph it, 2. 3x + y = 4 and x - y = 0, solve for x.

kirza4 [7]

Answer:

see the attachment
(x, y) = (1, 1)

Step-by-step explanation:

1. Since you have y > ..., the boundary line is dashed and the shading is above it (for y-values greater than the values on the line). The boundary line is ...

y = 2x+3

which has a y-intercept of 3 and a slope (rise/run) of 2. A graph is attached.

2. You can add the two equations to eliminate y:

(3x +y) +(x -y) = (4) +(0)

4x = 4

x = 1

1 - y = 0 . . . . substitute into the the second equation

1 = y . . . . . . . add y

The solution is (x, y) = (1, 1).
