x > -3

x < 3

-3 < x < 3

question didn't mention about "x is real number, or positive, or negative etc".. so we can't say anything more

for example: x can be -2,-1,0,1,2

but if only positive, x can be = 1,2

" " negative, x can be = -1, -2

Hope this helps ^-^

[6x4(15/5)[+[2^2+(1x-5)]

Vikki [24]

Answer:

Step-by-step explanation:

[6x4(15/5)]+[2^2+(1x-5)]

BIDMAS (aka PEDMAS etc.)

Brackets

Indices

Division/Multiplication

Addition/Subtraction

[6 x 4(15/5)] + [2^2 + (1x-5)]

[6 x 4(3)] + [2^2 + (-5)]

[6 x 4(3)] + [4 + -5]

[6 x 12] + [4 + -5]

[72] + [4 + -5]

72 + [-1]

72 + - 1

72 - 1

TIMED! Which expression is equivalent to is m∠4?

ratelena [41]

Answer:

The correct answer is first option m<2 + m<3

Step-by-step explanation:

From the figure we can see a triangle with angles, <1, <2 and <3

By angle sum property we can write,

m<1 + m< 2 + m<3 = 180°

m<1 = 180 - (m<2 + m<3) ----(1)

Also we know that, <1 and <4 are linear pairs

m<1 + m<4 = 180°

m<1 = 180 - m<4 ---(2)

Compare (1) and (2) we get

m<4 = m<2 + m<3

First answer the problem 3,216 divided by 8 and ur quotiont/answer u then will look at the answer and find the first diget and t

Shkiper50 [21]

Answer:

Quotient/Answer = 402

Hence the first digit is 4 and it's place value = hundreds

Step-by-step explanation:

Quotient = Dividend ÷ Divisor

Dividend = 3216

Divisor = 8

Quotient = 3216 ÷ 8

= 402

We are asked to find the place value of the first digit

Hence the first digit is 4 and it's place value = hundreds

{13x−12y=14 {11x−4=18y System of Equation Please explain

k0ka [10]

Answer:

x=2, y=1

Step-by-step explanation:

13x-12y=14

11x-4=18y or 11x-18y=4

13x-12y=14 /*3

11x-18y=4 /*(-2) then

39x - 36y=42 (1)

-22x+36y=-8 (2)

(1)+(2) 17x=34

-22x+36y=-8

x=34/17

-22x+36y=-8

x=2

-22*2+36y=-8

x=2

-44+36y=-8

x=2

36y=-8+44

x=2

36y=36

x=2

y=36/36

x=2

y=1

So is 1.5 greater than 3 ???

guapka [62]

Are you familiar with decimals? It's just an extension of the basic place value you've learned about before. Think of the number 21. "2" is in the tens place, and "1" is in the ones place.

Well, in this question, "1" is still in the ones place. HOWEVER, we have another number AFTER something called a decimal point (.), which shows that now we're getting into digits less than one. "5" is in what's called the tenths place, in which all the numbers are less than one. In other words, 1.5 is equal to 1 + 0.5. 0.5 is less than one, because it is a number in the tenths place.

Obviously, 1+1=2, right? And 2 is less than 3. Well, since 0.5 is even LESS than 1, 1+0.5 is less than 2. Therefore, 1.5 is less than 2, which is less than 3. So, 1.5 is LESS than 3, not greater than.

Answer: No, it's the other way around! 1.5 is LESS than 3.
