Mathematics
1 answer:
Lisa [10]3 years ago
3 0

Answer:

(49 - 29) + 1 =(50 - 29)

Step-by-step explanation:

The 20 comes from the subtraction of 29 in both sides of the previous step equality. In the following, I transcript the complete procedure and I add the step that you need to understand why 20 appears (in bold numbers):

29+20=49

49+1=50

(49 - 29) + 1 =(50 - 29)

20+1=21

50-29=21

hence, it was only nesseraty to subtract 29

Pie Chart 3: Drinking Water Services (of 7.8 Billion People)
bija089 [108]

Answer:

access to safe drinking water is a fundamental need and human right. Securing access for all would go a long way in reducing illness and death, especially among children. “Safely managed” drinking water services represent an ambitious new rung on the ladder used to track progress on drinking water.  Since 2000, 2 billion people have gained access to safely managed services (i.e., accessible on-premises, available when needed, and free from contamination). In 2020, 5.8 billion people used safely managed services and a further 2 billion people  used basic services ( improved sources within 30 minutes per round trip to collect water).

However, 771 million people still lacked even a basic level of service, including 282 who used a “limited” water service (improved source from which water collection exceeds 30 minutes), 367 million who used unimproved sources and 122 million who still collected drinking water directly from rivers, lakes, and other surface water sources. The data reveal pronounced disparities, with the poorest and those living in rural areas least likely to use a basic service. In most countries, the burden of water collection continues to fall mainly to women and girls.

10 1/2 cups of flour are needed to make 3 loaves of bread. How many cups are needed for 12?
Mazyrski [523]

Answer:

42 cups of flour

Step-by-step explanation:

12 is 4 times more than 3 (3 × 4 = 12), so we know that we need 4 times 10 1/2 (equal to 10.5) cups of flour.

All we need to do for this is do 10.5 × 4 = x and solve for x.

10.5 × 4 = 42 cups of flour

a system of equations is shown below: y=3x-7 and y=2x+7. what is the solution to the system of equations?
castortr0y [4]
A system of equations means that both equations need to be true in the same time.
Since y is equal with 3x-7 and 2x+7 then those must be equal with eachother.
3x-7=2x+7
3x-2x=7+7
X=14
Now that we know x use any given equation of y and substitute x with 14
Y=3•14-7=35
Solution: x=14, y=35
