Can someone help me with these two

Mathematics
1 answer:
LenaWriter [7]3 years ago
4 0

Answer:

The first equation answer is 10

And the second one 6

Step-by-step explanation:

The first equation

2/5 x +3= 2/3x +1/3

2x + 15/5 = 6x+3/9 the cress cross

9(2x + 15) = 5(6x + 3)

18x + 135 = 30x +15

135-15 = 30x - 18x

120 = 12x

120/12 =12x/12

10 = x

X =10

The second one

-2.6b +4 =0.9b - 17

-2.6b - 0.9b = - 17 - 4

-2.6b + (-0.9b) = - 17 + (-4)

-3.5b = - 21

-3.5b/-3.5 = - 21 /-3.5

B= 6

HELP! ASAP!

Step-by-step explanation:

2.

the volume of the box is

length × width × height = 13×13×13 = 13³ = 2197 cm³

the ratio of the density indignation tells us that every cm³ of soil weighs 1.33 g (or every unit of 1.33g soil fits into 1 cm³).

we have 2197 cm³.

their weight is

2197 × 1.33 = 2,922.01 g

so, the filled box clearly exceeds the max. weight of the window ledge, and it is NOT safe to put it there.

b

yes, it would be a little bit less dense.

because every bit of weight you put on top of something increases the pressure on and therefore the density of that something.

13 please I have no idea what the steps for this is
Ilya [14]

Answer:

UV=142

Step-by-step explanation:

21x-13=10x+31

+13 +13

21x=10x+44

-10x=-10x

11x=44

÷11 ÷11

x=4

now substitute 4 in place of x (only have to solve one)

21(4)-13= 71

now multiply your answer by 2

71×2=142

Please help me with this translating trigonometry graphs question. Brainliest and Points Available.
andreev551 [17]

According with the definition of translation, we conclude that the equations of graphs M and N are m(x) = f(x - 5) and n(x) = f(x) - 2, respectively.

<h3>How to apply translations on a given function</h3>

<em>Rigid</em> transformations are transformation such that the <em>Euclidean</em> distance of every point of a function is conserved. Translations are a kind of <em>rigid</em> transformations and there are two basic forms of translations:

Horizontal translation

g(x) = f(x - k), k ∈ \mathbb {R}     (1)

Where the translation goes <em>rightwards</em> for k > 0.

Vertical translation

g(x) = f(x) + k, k ∈ \mathbb {R}     (2)

Where the translation goes <em>upwards</em> for k > 0.

According with the definition of translation, we conclude that the equations of graphs M and N are m(x) = f(x - 5) and n(x) = f(x) - 2, respectively.
