Solve the system of equations by substitution y= 7x-10 y=-3

Mathematics

coldgirl [10]4 years ago
5 0
Y = 7x - 10 . . . (1)
y = -3 . . . (2)

Putting (2) into (1) gives:
-3 = 7x - 10
7x = -3 + 10q = 7
x = 7/7 = 1

Therefore, solution = (1, -3)

A monkey weighs 8.2 kilograms. How many grams does the monkey weigh? Use the number of zeros of the product when multiplying a n
Kobotan [32]

Answer:

m = 8.2 × 10³ grams

Step-by-step explanation:

Given that,

The weight of a monkey = 8.2 kilograms.

We need to convert its mass from kilograms to grams.

We know that,

1 kg = 1000 grams

or

1 kg = 10³ grams

In 8.2 kg,

8.2 kg = 8.2 × 10³ grams

Hence, the weight of the monkey is equal to 8.2 × 10³ grams.

HELP!! What is the value of x??
nordsb [41]

Answer:

X = 41°

Step-by-step explanation:

<h3>Sum of interior Angles of a ∆ is 180°</h3>

\angle1  +  \angle2 +  \angle3 = 180 \degree

Here  \\  \angle1 = 105 \degree \\  \angle2 =  ? \\  \angle3 = x

\angle4 = 146 \degree

here \:  \angle2 +  \angle4 = 180 \degree \\ \: (liner \: pair \: angle) degree\\ \angle2  + 146\degree = 180 \degree \\ \angle2 = 180 \degree - 146\degree \\ \angle2 = 34\degree

\angle1  +  \angle2 +  \angle3 = 180 \degree  \\ 105\degree + 34\degree + x = 180\degree \\ 139\degree + x = 180\degree \\ x = 180\degree - 149\degree \\ x = 41\degree
